NBME Practice Test

โ–ถ

If you have ever scrolled around the National Board of Medical Examiners website looking for your CBSE order, a missing score report, or that elusive free 120-question USMLE sample, you have probably hit the My NBME sign-in screen. And then frozen for a second wondering: is this the right portal? Different from the USMLE eRA login? Different from ECFMG's MyIntealth?

Short answer โ€” yes, it is its own thing, and yes, almost every medical student, IMG, residency applicant, and self-assessment buyer ends up using it. The portal lives at apps.nbme.org, and it is the single doorway to nearly every NBME-branded service that is not the actual USMLE exam itself.

This guide walks you through every corner of the My NBME account portal. We will cover account creation (and what to do when your verification email never arrives), purchasing CBSE and CBSSA practice forms, grabbing the free 120 USMLE samples, finding test reports once the dust settles after your real USMLE attempt, and the strange middle ground between My NBME, the USMLE eRA portal, and the FSMB/ECFMG MyIntealth ecosystem.

You will also get a no-nonsense look at the technical issues that bite users โ€” browser compatibility, time zone weirdness, mid-test crashes โ€” plus a few honest workarounds that the NBME help desk does not always volunteer.

By the end you will know exactly which login goes where, which products live behind which paywall, and how to recover when something breaks at 11pm the night before your shelf exam. We will also point you to NBME-aligned practice sets you can use right now to gauge whether your assessment score is actually predictive of what will happen on test day.

What My NBME Actually Is (and What It Is Not)

My NBME is the consumer-facing account system the National Board of Medical Examiners uses for everything except the actual USMLE Step exams. Think of it like a slightly old-fashioned online store crossed with an assessment delivery platform. When you log in, you land on a dashboard that lists your purchased products, ongoing self-assessments, and prior score reports. That is mostly it. No flashy widgets, no nudge notifications, no gamified progress bars โ€” just a list of links to things you paid for.

The portal handles three types of activity: purchasing (CBSE, CBSSAs, subject exams, ISA self-assessments), taking the timed assessment in your browser, and viewing the score report afterwards. If you bought a product from NBME's storefront, the access lives here. If you took a real USMLE attempt โ€” Step 1, Step 2 CK, Step 3 โ€” that score lives in the USMLE eRA portal at usmle.org, not here. Many students get this wrong on their first login and spend forty minutes hunting for a score that was never going to be in this account.

Some institutional orders also flow through this account. If your medical school assigns you a CBSE during a clerkship, the test code typically gets activated against your My NBME login, and the score report posts here within 24 hours of the test session closing. The institution gets the aggregate report; you get your individual one.

Three Portals, Three Purposes

My NBME (apps.nbme.org) handles practice tests, CBSE, CBSSA, self-assessments, free 120 samples, and subject exam reports. USMLE eRA Portal (usmle.org) handles real USMLE Step 1/2/3 registration and official score reporting. ECFMG MyIntealth handles IMG credentialing, OASIS replacement, and certification verification. The three accounts do not share passwords, but you can use the same email for all three.

Creating Your My NBME Account

Registration is free and takes about three minutes if nothing goes wrong. Head to apps.nbme.org, click Create Account, and you will be asked for the basics โ€” full legal name (matching whatever government ID you would use for testing), date of birth, email, and a password. NBME enforces a fairly standard password rule: at least eight characters, mixed case, one number, one symbol. Stick to that and move on.

After you submit, the system fires a verification email. This is where the first real headache shows up. The email usually arrives within two minutes from noreply@nbme.org, but a non-trivial slice of users โ€” particularly anyone using a school-issued .edu address with aggressive spam filtering โ€” never sees it. Before you panic and create a duplicate account (which will lock both), do these three things in order: check spam and the Promotions tab in Gmail, wait fifteen minutes, then check whether your school's IT blocks bulk mail from .org senders.

If the email is genuinely missing after an hour, request another from the login page rather than re-registering. Re-registering with the same email and birthdate is the easiest way to trigger a soft account lock that requires a human at NBME to release.

Why your name has to match your ID exactly

If you ever plan to use this account for an institutionally-assigned CBSE or a paid CBSSA where score reporting matters, your registered name needs to match your government-issued photo ID. Mismatched names are the most common reason for a score report to be held. Fix it before you ever buy a product โ€” once an order is placed, the order is locked against the name on file.

International students should use the romanized version of the name that appears on their passport, not a transliteration of how it is pronounced. The NBME uses these records when issuing official transcripts to residency programs, and inconsistent name data has a way of surfacing two years later at the worst possible moment.

What You Can Do Inside My NBME

๐Ÿ”ด Buy Self-Assessments

Purchase CBSSA forms (Step 1 style), CCSSA forms (Step 2 CK style), and CMSA forms (Step 3 style). Forms 25-32 are the current rotation.

๐ŸŸ  Take the Free 120

Access the free USMLE practice sample tests โ€” Step 1, Step 2 CK, and Step 3 versions, no payment required, but you must be logged in.

๐ŸŸก Activate Test Codes

Redeem codes from your school for a CBSE or shelf exam assigned during clerkships and basic science blocks.

๐ŸŸข View Score Reports

After any self-assessment closes, the detailed performance feedback and predicted score band appear in your dashboard within 24-72 hours.

๐Ÿ”ต Manage Subject Exams

If you wrote a clerkship subject exam (shelf), the historical score report shows here once your institution releases it.

๐ŸŸฃ Update Profile Info

Change your password, contact details, and security questions. Name changes require document upload.

Buying Practice Forms โ€” CBSSA, CCSSA, and the Free 120

The bulk of why anyone visits My NBME comes down to assessment purchases. Once you are logged in, click Self-Assessment Services from the top menu. The catalog splits cleanly by exam type. CBSSAs are Step 1 style, CCSSAs are Step 2 CK style, and CMSAs are Step 3 style. Each costs around $60 for the standard timed version and roughly $20 more for the expanded feedback option, which gives you a question-by-question breakdown rather than just topic-level performance.

Pick a form, add to cart, and check out with any major credit card. International cards work, but billing addresses outside the United States occasionally trigger a manual fraud review that delays activation by 24 hours. If you are buying the day before your planned practice session, do not cut it that close.

The product appears in your My Assessments tab once payment clears, and you have six months from purchase to launch it. Once launched, you have several hours to complete the timed form โ€” different products have slightly different time limits, so check the product page before you start.

The free 120 USMLE practice samples

NBME publishes a free 120-question practice block for each USMLE step. These are arguably the most under-appreciated free resource in the entire test-prep ecosystem because they come from the same item bank that retired questions are pulled from. Items rotate periodically โ€” the current Step 1 free 120 is broken into three 40-question blocks and lives under Take an Assessment, then Free Practice. You do not need a paid product, but you do need a logged-in account.

Score interpretation for the free 120 is unofficial โ€” there is no equated three-digit score, just a percent-correct figure. Most users find these sets a little easier than the equivalent CBSSA, so do not over-read a strong performance. Use them for content review rather than score prediction.

Why CBSE matters for IMGs and DOs

For international medical graduates targeting USMLE pathways, the Comprehensive Basic Science Exam (CBSE) sits in an odd middle ground. It is the same item difficulty as Step 1 but is administered through institutional channels or as an individual purchase via My NBME. Many Caribbean medical schools require a passing CBSE before approving a Step 1 sit. DO students take their own version, the COMSAE, which is administered through the NBOME โ€” not the NBME โ€” so do not look for it here.

If your school has assigned you a CBSE, you will receive a registration code by email. Enter it under Activate Code on the dashboard, link it to your scheduled test date, and the test will become available at the start window. You take it under proctored conditions at a Prometric center.

NBME Product Categories Explained

๐Ÿ“‹ Tab 1

Comprehensive Basic Science Self-Assessments. Step 1 style, ~$60 each, 4 blocks of 50 questions, 4h 15m timed mode. Forms 25-32 are the active rotation. Use as predictive score generators. Most students take Form 25 (oldest) early and save Forms 31-32 for the final two weeks.

๐Ÿ“‹ Tab 2

Comprehensive Clinical Science Self-Assessments. Step 2 CK style, similar pricing, 4 blocks. Forms 11-14 represent the current pool. Predictive validity is high โ€” most students score within 8-12 points of their actual Step 2 CK three-digit score.

๐Ÿ“‹ Tab 3

Shelf exams covering Medicine, Surgery, Pediatrics, OB/GYN, Psychiatry, Family Medicine, and Neurology. Administered through your medical school during clerkships. Score reports post to My NBME after institutional release.

๐Ÿ“‹ Tab 4

Step 1, Step 2 CK, and Step 3 each have a free 120-question sample available at no charge through My NBME. Three blocks of 40 questions, untimed by default but can be set to timed mode. Score reporting is percent correct only.

๐Ÿ“‹ Tab 5

International Foundations of Medicine self-assessments are similar to CBSSAs but designed for non-US programs and pre-clinical international students. Less commonly purchased; mostly used by overseas medical schools for internal benchmarking.

Finding Your Test Report After a Real USMLE Attempt

Here is the thing people get wrong: if you just took Step 1 or Step 2 CK, your official score report does not appear in My NBME. It lives in the USMLE eRA portal at usmle.org. The two accounts are separate, and the USMLE registration system is run jointly by the NBME and the FSMB rather than NBME alone. Real Step scores release on Wednesdays โ€” typically four to six weeks after your test date โ€” and you will get an email letting you know your report is ready in the eRA portal.

What does appear in My NBME after a real Step attempt is nothing, unless your school separately ordered an aggregate report or you bought one of the post-exam item-level review products. The portal will however still hold your old CBSSA scores indefinitely, which is useful when retroactively gauging how predictive each form was for your final outcome.

ISA self-assessment products

The International Foundations of Medicine (IFOM) program runs the ISA suite โ€” basic science and clinical science self-assessments designed for international medical schools. The Basic Science Self-Assessment and Clinical Science Self-Assessment products live in the same My NBME catalog but are filtered by region. If you do not see them in your storefront, your account region defaulted to the US menu. Email registrationhelp@nbme.org with your residence and they will toggle the catalog. ISA products are a reasonable predictor for IFOM exam performance but should not be substituted for CBSSAs if your end-goal is USMLE Step 1.

My NBME vs USMLE eRA Portal vs MyIntealth

This trips up almost every IMG at least once. Three different accounts, three different portals, three different functions โ€” all under the broad NBME-FSMB-ECFMG umbrella.

My NBME (apps.nbme.org) handles self-assessments, CBSE, subject exams, and the free 120 practice sets. The USMLE eRA portal (apps.usmle.org) handles actual USMLE Step registration, scheduling, and official score reporting. MyIntealth (myintealth.ecfmg.org) replaced the older OASIS system and handles ECFMG credentialing, USMLE eligibility verification for IMGs, and certification status. None of these accounts auto-link. You can โ€” and should โ€” use the same email address for all three to keep things organized, but you will need three separate password resets if you forget them.

For DOs taking COMLEX-USA, none of these portals apply. COMLEX uses the NBOME portal at app.nbome.org. The naming similarity is not an accident โ€” both are testing boards that share IT infrastructure conventions โ€” but the accounts are entirely separate.

Common Technical Issues and Real Fixes

The My NBME platform runs reliably on the latest Chrome, Firefox, and Edge on desktop. Safari technically works but generates an outsized share of support tickets, especially on older macOS. If Safari misbehaves, switch to Chrome and move on.

Browser checklist before any timed form

Forty minutes before launch, close every other tab. Disable all extensions โ€” especially ad blockers, password managers, and grammar tools. Switch off battery saver. Hardwire your network if possible. Run the system check from the NBME platform demo page first.

Time zone confusion

The platform timestamps everything in US Eastern Time. Launch windows for institutional CBSEs may look wrong on your local clock. Always convert from ET, and remember the US shifts between EST and EDT twice a year.

Lost password reset emails

The reset email comes from donotreply@nbme.org โ€” a different prefix from the registration email. Allowlist the full nbme.org domain. Outlook tends to drop these into Junk even when registration mail arrived fine.

Enable 2FA

NBME added optional 2FA in 2022. It is off by default. Turn it on the moment your account is verified. Taken-over accounts have had purchased forms wasted.

Score Reports and Predicted Score Bands

Every CBSSA, CCSSA, and CMSA produces a score report within 24 to 72 hours of session close. The headline is a three-digit equated score on the same scale as the real USMLE Step exam. Most students score within 10 points of the form's prediction on test day. Newer forms (30-32 for Step 1, 13-14 for Step 2 CK) are the most tightly calibrated.

Pre-Assessment Checklist

Account name matches your government photo ID exactly
Email and 2FA are enabled and verified
Payment card billing address is current
You have at least one uninterrupted four-hour window blocked off
Latest Chrome or Firefox installed; extensions disabled
Wired network or strong wifi within 3 meters of router
You have decided whether to pay extra for expanded feedback
You know how to interpret the three-digit predicted score band

Special Considerations for International Medical Graduates

For IMGs, My NBME is one of three accounts you will touch during USMLE prep. Keep them straight: My NBME for practice, eRA for real exams, MyIntealth for ECFMG credentialing. Without an active ECFMG application in MyIntealth you cannot register for the actual USMLE โ€” but you can still buy and take CBSSAs in My NBME with no ECFMG application at all.

Some IMGs use My NBME's CBSE product as a paid stand-alone if their home school does not offer institutional administration. The individual route runs roughly $150-$200 for a proctored CBSE at a Prometric center. The score report comes back to My NBME within 7-10 days.

Currency and payment notes

NBME charges in US dollars regardless of country. Currency conversion happens at the card-issuer level. Multi-currency cards (Wise, Revolut) avoid bad domestic FX rates. NBME does not accept PayPal, Apple Pay, or cryptocurrency.

My NBME Self-Assessments: Honest Trade-Offs

Pros

  • Highest predictive validity of any paid practice resource โ€” within 10 points of real Step score
  • Items come from the actual NBME item bank, retired questions only but same calibration
  • Free 120 USMLE samples are arguably the best free practice block available
  • Score reports include three-digit equated scores on the same scale as real Step exams
  • Expanded feedback option lets you see your individual answer choices and explanations
  • Six-month activation window gives generous flexibility between purchase and launch

Cons

  • No question explanations on the standard (non-expanded) feedback version
  • Browser-only platform with occasional Safari incompatibility
  • $60 per form adds up quickly โ€” eight forms is nearly $500
  • Sparse user interface compared to UWorld or AMBOSS
  • No mobile app โ€” you must take assessments on desktop or laptop
  • Customer service email response time can stretch to 3-5 business days

Which Forms to Take, and When

A common dedicated plan uses two to four CBSSAs across the final six to eight weeks. Take Form 25 or 26 about six weeks out as a baseline. Take a middle-rotation form (28 or 29) at the three-week mark. Save Form 30, 31, or 32 โ€” the newest, most predictive โ€” for your final week. That last score is your real predicted Step 1 number, give or take five points.

For Step 2 CK, the CCSSA approach is similar. Many students report their CCSSA Form 14 score landed within two or three points of their actual Step 2 CK score. Do not burn five CBSSAs in two weeks. Space them out so you have a clean predictor right before test day.

Pairing assessments with practice questions

NBME self-assessments are diagnostic, not learning resources. Use them to find gaps, then return to UWorld, AMBOSS, or a textbook to relearn the content. Take a form, review wrongs, pick three weak topics, drill them in your primary bank for a week, then take the next form. Subject-aligned drills surface patterns that broad CBSSAs miss.

Drill High-Yield Pathology Questions

Bottom Line

My NBME is one of those tools where five minutes of setup saves you hours of confusion later. Create the account early, verify the email, enable 2FA, and use the free 120 well before you spend a cent on a paid form. When you do buy, start with an older CBSSA to anchor your baseline, work through the gaps with a primary question bank, and only return for the newer forms once you are within striking distance of your target score.

Keep the three portals straight in your head โ€” My NBME for practice and CBSE, USMLE eRA for the real exam and official scores, MyIntealth if you are an IMG dealing with ECFMG. They do not talk to each other, they will not share passwords, and confusing them is the single most common reason students miss a deadline.

If something goes wrong mid-test, breathe, log back in within fifteen minutes, and email selfassessment@nbme.org if the timer did not pause cleanly. The support team is slow but they will resolve legitimate technical issues. Just do not start a new attempt or buy a replacement before they respond โ€” that closes their ability to restore your original session.

Good luck with whatever assessment brought you here. Whether it is a CBSE for school, a CBSSA before Step 1, the free 120 to test the waters, or just hunting down an old subject exam score โ€” the portal is unglamorous but it works once you know where to click.

NBME Questions and Answers

Where do I find my official USMLE Step score in My NBME?

You don't. Real USMLE Step scores live in the USMLE eRA portal at usmle.org, not in My NBME. My NBME holds your self-assessment and CBSE scores only. The eRA portal releases real Step scores on Wednesdays, typically four to six weeks after your test date.

How much does a CBSSA cost on My NBME?

A standard timed CBSSA costs around $60. The expanded feedback version, which gives you a question-by-question answer breakdown with brief explanations, costs roughly $80. CCSSAs and CMSAs are similarly priced. You have a six-month activation window from purchase to launch.

Is the free 120 sample worth taking?

Absolutely. The free 120-question USMLE practice block uses items from the actual NBME bank and is one of the highest-quality free resources available. Just don't use it for score prediction โ€” it only reports percent correct, not an equated three-digit score, and it tends to run slightly easier than a current CBSSA.

What's the difference between My NBME and MyIntealth?

My NBME (apps.nbme.org) is for self-assessments and practice products run by the NBME. MyIntealth (myintealth.ecfmg.org) is the ECFMG portal for international medical graduate credentialing โ€” verifying your medical school, tracking your ECFMG certification status, and confirming USMLE eligibility for IMGs. Different organizations, different accounts.

My verification email never arrived. What now?

Check spam and the Promotions tab first. Wait fifteen minutes, then request a fresh verification email from the login page โ€” do not re-register, since duplicate accounts trigger a soft lock that needs human intervention to release. If still nothing after an hour, contact registrationhelp@nbme.org and allowlist the entire nbme.org domain in your mail settings.

Can I take a CBSSA on my iPad or phone?

No. My NBME's assessment platform is desktop-only. There is no mobile app, and the browser experience on tablets is not officially supported. Use a laptop or desktop with a current Chrome, Firefox, or Edge browser. Safari technically works but has more reported issues than the other three.

My browser crashed during my CBSSA โ€” did I lose my money?

Probably not. If you log back in within fifteen minutes, the assessment resumes from your last answered question with the timer paused. If you miss the fifteen-minute window, email selfassessment@nbme.org with your order ID and crash time โ€” they can restore the session manually within 24 hours. Don't start a new attempt before they respond.

How predictive is a CBSSA score of my actual USMLE Step score?

Quite predictive โ€” most students score within 10 points of their CBSSA prediction on the real exam, and within 5 points if the CBSSA was taken within two weeks of test day. Newer forms (CBSSA 30-32, CCSSA 13-14) are the most tightly calibrated. Older forms can drift slightly because the item statistics get re-equated as content evolves.
