Worked examples: how to reason through DAT questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: Which of the following terms best describes the relationship between (2R,3S)-2,3-dibromobutane and (2S,4R)-2,4-dichloropentane?

  1. Enantiomers
  2. Diastereomers
  3. Identical compounds
  4. Constitutional isomers

Answer: D. Constitutional isomers

Explanation:

The answer is constitutional isomers. Constitutional isomers differ in how atoms are connected, and these two compounds have different carbon skeletons and different halogen substituents, so connectivity is clearly different. Strictly, they are not isomers at all, because their molecular formulas differ, but this is the only option that describes a connectivity difference.

Enantiomers are wrong because they are mirror-image stereoisomers with the same connectivity. Diastereomers are wrong for the same reason: they are stereoisomers, so connectivity must match. Identical compounds are wrong because the structures plainly differ.

Rule to remember: compare connectivity first. If it differs, stereochemical terms do not apply.

Example 2

Question: Which one is the smallest?

  1. 5/46
  2. 11/63
  3. 7/36
  4. 1/5
  5. 2/9

Answer: A. 5/46

Explanation:

The answer is 5/46. The quickest reliable method is converting each fraction to a decimal. 5/46 is about 0.1086, which is lower than 11/63 at about 0.1746, 7/36 at about 0.1944, 1/5 at 0.2000 and 2/9 at about 0.2222.

Each wrong option is larger, so none can be the smallest. You can also spot this by estimation: 5/46 is a little over one tenth, while the others are all closer to one fifth.

Rule to remember: when fractions have unrelated denominators, convert to decimals or compare against a benchmark such as 1/5, rather than hunting for a common denominator.

Example 3

Question: Which functional group is present in a ketone?

  1. -CHO (terminal carbonyl)
  2. An internal C=O flanked by two carbons
  3. -COOH
  4. -COO-

Answer: B. An internal C=O flanked by two carbons

Explanation:

The answer is an internal C=O flanked by two carbons. A ketone has a carbonyl carbon bonded to two other carbon atoms.

-CHO is a terminal carbonyl, which is an aldehyde, since the carbonyl carbon carries a hydrogen. -COOH is a carboxylic acid, where the carbonyl carbon also bears an OH group. -COO- is an ester or carboxylate, where the carbonyl carbon is attached to an oxygen.

Rule to remember: look at what the carbonyl carbon is bonded to. Two carbons means ketone, a hydrogen means aldehyde, and an oxygen means an acid or ester.

How to use these practice tests

Start by reading the official ADA candidate guide so you know the rules for eligibility, retakes and rescheduling. Then take one of our section practice tests, such as Survey of Natural Sciences, to see where you stand. Do not worry about the score at this stage; note which topics you miss.

Next, work through the topic sets for your weak areas. For science, try Cellular Metabolism, Stoichiometry and Stereochemistry. After each set, read the explanations for every question you missed and write down the rule behind it.

Give the skill-based sections regular short sessions. Practise Pattern Folding and Angle Ranking repeatedly, because speed improves with repetition. Use Probability for quantitative practice and Scientific Passages for reading.

Our questions are written by us and are not real exam questions, so treat them as practice for reasoning, not as a preview of the test. Before test day, repeat the section practice tests and compare them with your first attempt. Book your date with the retake waiting period in mind.

DAT Questions and Answers

What is a good score on the DAT?

A competitive DAT score for most dental schools is 20 or above, which places you around the 75th percentile. The average score for admitted students at U.S. dental schools is typically between 19 and 21 across all sections. Top-tier programs may expect scores of 22 or higher. The Academic Average and Perceptual Ability scores are often weighted most heavily by admissions committees.

How long is the DAT exam?

The DAT takes approximately 4 hours and 15 minutes to complete, including an optional tutorial and break. The actual testing time is around 3 hours and 15 minutes. You receive a 30-minute break between the Survey of Natural Sciences section and the Perceptual Ability Test. Time management is critical since each section is independently timed.

How much does the DAT cost to take?

The DAT costs $360 per attempt, paid directly to the American Dental Association when you register through the ADA website. If you need to retake the exam, you must pay the full fee again. There are no fee waivers available from the ADA, though some pre-dental organizations and universities may offer financial assistance to eligible students.

How do I register for the DAT?

You register for the DAT through the ADA's official website at ada.org. You must create a Dentpin ID, complete the online application, and pay the exam fee. After approval, you can schedule your test at any Prometric testing center. Registration is typically processed within a few business days, and you can schedule your exam up to six months in advance.

Can I retake the DAT if I am not satisfied with my score?

Yes, you can retake the DAT up to three times. You must wait at least 90 days between each attempt. After three attempts, you need special permission from the ADA to take the exam again. All scores from every attempt are reported to dental schools, so most advisors recommend thorough preparation before your first sitting.

What subjects are covered in the Survey of Natural Sciences section?

The Survey of Natural Sciences section includes 100 questions across three disciplines: biology (40 questions), general chemistry (30 questions), and organic chemistry (30 questions). Biology covers cell biology, genetics, anatomy, and ecology. General chemistry spans stoichiometry, thermodynamics, and acid-base reactions. Organic chemistry focuses on reaction mechanisms, functional groups, and stereochemistry.

What is the Perceptual Ability Test on the DAT?

The Perceptual Ability Test (PAT) is a unique section with 90 questions completed in 60 minutes. It measures spatial reasoning and visual perception skills essential for dentistry. The section includes six question types: apertures, view recognition, angle ranking, hole punching, cube counting, and pattern folding. This section cannot be studied from a textbook and requires dedicated spatial reasoning practice.

Who is eligible to take the DAT?

To take the DAT, you must have completed at least one year of college coursework, including biology and general chemistry. There is no specific degree requirement, and you do not need to have completed all prerequisite courses before testing. Most students take the DAT after completing two years of undergraduate study, typically during the spring or summer before applying to dental school.

What is the passing score for the DAT?

The DAT uses a 200–600 scale in 10-point increments, with acceptable scores determined by individual dental programs. (Verified Oct 15, 2026 against American Dental Association (ADA), Council on Dental Education and Licensure.)
