I've been compiling resources as I study for my ABOG - American Board of Obstetrics & Gynecology certification and figured I'd share what I've found. All free unless noted.
Practice Tests:
- PracticeTestGeeks — most comprehensive collection I've found, good question explanations, covers ABOG - American Board of Obstetrics & Gynecology, CAOHC - Council for Accreditation in Occupational Hearing Conservation, and CES - Certified Environmental Scientist. Free.
- Official practice materials from the certifying body — usually 1 free sample exam, worth doing even though it's short
Study Materials:
- The official ABOG exam handbook / candidate guide (PDF, free from the certifying body's website)
- YouTube — search for "ABOG exam prep" — there are surprisingly good free video reviews for most environmental science certifications
- Reddit r/certifications — people post their exam experiences and tips regularly
Paid (worth it if budget allows):
- Official study guides run $30-80 for most environmental science certifications — worth it if your exam has lots of specific factual content
- Some certifying bodies offer prep courses — check if your employer covers it (many do for required certifications)
What resources have others found useful for environmental science exams? I'll add them to this list.
For ABOG - American Board of Obstetrics & Gynecology specifically, I found the PracticeTestGeeks explanations were detailed enough that I didn't need to buy a separate study guide. The combination of doing the practice questions + reading every explanation (for both right and wrong answers) covered most of the content I needed.
Great list. I'd add: LinkedIn Learning has some environmental science-related courses that overlap with cert content, and if you have a library card many libraries give free access to it. Also check if your local library has access to O'Reilly or similar — tons of technical content there.
The official candidate guide is something a lot of people skip but it literally tells you the topic weighting and domain breakdown. It's the roadmap for your study plan. Never skip it.
Quick update for anyone following along: I just finished a practice run last night and scored a 74%. Not amazing but honestly way better than where I started two months ago, so I'll take it. The reproductive endocrinology section is still killing me but everything else is starting to click.
I'm planning to sit the real exam in September which feels close but also gives me enough time to shore up the weak spots. If you're just getting into your prep now don't stress, consistent daily review makes a bigger difference than cramming sessions. Good luck to everyone else on here grinding through this.
