OAT Practice Test and Optometry Admission Test Practice Questions From Your Own Notes and PDFs

Upload your OAT study guide, biology, chemistry and physics notes or your own summaries and the AI writes unlimited practice questions with an answer key and explanations in seconds. Drill the natural sciences, reading comprehension, physics and quantitative reasoning content instead of re-reading a review book you have already memorized.

Your study files are processed securely and deleted automatically after your practice questions are built.

In short: to build OAT practice questions, upload your study guide, science notes, physics notes or your own summaries, and the AI writes practice questions with an answer key and explanations in seconds. The Optometry Admission Test has 230 questions across four tests (Survey of the Natural Sciences, Reading Comprehension, Physics and Quantitative Reasoning) in about 5 hours. Scores use a scaled 200 to 400 range where 300 is the median, and a competitive Academic Average is roughly 320 or higher. Because the natural sciences test is the largest, drill biology, general chemistry and organic chemistry hardest, and keep physics sharp too.

What an OAT practice question generator does

Test yourself on your own study material, not a set you have memorized

By the third pass through an OAT review book you start recognizing the answer instead of reasoning through the science. You see a familiar physics problem and remember the choice, not the equation behind it. This tool flips the source. You upload what you are actually studying, a chapter from your biology notes, your organic chemistry summaries or a physics problem set, and the AI can turn a document into practice questions that are brand new every time. A wrong answer points straight back at the topic you need to review, and a fresh set is always one upload away.

Works with any review book or notes

Upload a review book chapter, your biology, chemistry or physics notes, a lecture PDF or pages you photographed. If the file explains a science, physics or math concept, the generator can build practice questions on it.

Target one subject at a time

Shaky on organic chemistry mechanisms or physics kinematics? Upload the notes for one subject and narrow your practice to where your accuracy is soft, rather than re-answering questions you already have cold.

Fresh questions every session

Generate a new set every time so you are testing recall, not memory of a specific question. Repeated retrieval on unseen items is what pushes a plateaued score up toward a competitive number.

OAT sections, questions and time

The OAT has four tests with the question counts and time limits below. Use this as a study map and confirm the current structure on the ADA website.

Section Questions Time What it covers
Survey of the Natural Sciences 100 90 min Biology (40), general chemistry (30) and organic chemistry (30).
Reading Comprehension 50 60 min Reading and interpreting scientific passages you have not seen before.
Physics 40 50 min Stand-alone physics problems (the OAT has physics where the DAT has perceptual ability).
Quantitative Reasoning 40 45 min Math and applied problems with an on-screen calculator.

The counts tell you where to spend your time. The Survey of the Natural Sciences is the biggest test at 100 questions, so biology, general chemistry and organic chemistry deserve the most review, and those three subjects also feed your Academic Average and Total Science score. Build knowledge sets from your notes on each subject, then keep drilling until your accuracy is even, since a single weak subject can pull down the Academic Average that optometry schools weigh most heavily. Physics is the section that sets the OAT apart from the DAT, so give it dedicated practice rather than treating it as an afterthought.

Simple process

How to make OAT practice questions in 4 steps

1
Upload your material
Drop in your review book chapter, biology, chemistry or physics notes, a lecture PDF or your own summaries. Scanned and handwritten pages are read with OCR.
2
Set the drill
Pick the question count and difficulty. Run a short warm-up on one subject or a longer mixed set across biology, chemistry, organic and physics.
3
AI writes questions
The AI reads your content and writes OAT style multiple choice questions with an answer key and clear explanations.
4
Review and repeat
Score the set, read the explanation behind every miss, then generate a fresh drill on just those weak subjects and go again.

Who uses this to prep for the OAT

Pre-optometry students

Undergraduates applying to optometry school who need a strong Academic Average. Upload your biology, general chemistry, organic chemistry and physics notes and drill the natural sciences test, which is the largest and carries the most weight in your reported scores.

Prep course and self-study candidates

If you are working through an OAT prep course or a review book, turn each subject into fresh questions the moment you finish it, so recall is tested immediately instead of months after you took the class.

Retakers lifting a weak subject

When one science or physics subject dragged your Academic Average last time, you do not need to redo everything. Upload just those notes, drill until the misses stop, and turn the subject that capped your score into one that lifts it.

OAT practice questions, answered

How many questions are on the OAT?
The Optometry Admission Test has 230 multiple choice questions across four tests: Survey of the Natural Sciences (100), Reading Comprehension (50), Physics (40) and Quantitative Reasoning (40). Total seated time is about 5 hours, including a tutorial and an optional break. If your notes are on paper, run them through an OCR tool like DocuOCR first.
How is the OAT scored?
OAT scores use a scaled range of 200 to 400, where 300 is the median (50th percentile), reported in 10-point intervals. The Academic Average is the average of your six subject scores: Biology, General Chemistry, Organic Chemistry, Physics, Reading Comprehension and Quantitative Reasoning. The Total Science score covers Biology, General and Organic Chemistry and Physics.
What is a good OAT score?
A competitive OAT Academic Average is roughly 320 or higher, while around 300 sits at the median, or 50th percentile. Because scores run from 200 to 400 in 10-point steps, moving from 300 to 320 is a meaningful jump. Aim for balanced subject scores, since optometry schools review your full profile rather than one strong section.
What sections are on the OAT?
The OAT has four tests. The Survey of the Natural Sciences covers biology, general chemistry and organic chemistry. Reading Comprehension asks you to interpret scientific passages you have not seen before. Physics presents stand-alone problems. Quantitative Reasoning covers math and applied problems with an on-screen calculator. The science and math content is where uploading your own notes helps most.
What is the difference between the OAT and the DAT?
The biggest difference is that the OAT has a Physics section and no Perceptual Ability Test, while the DAT has Perceptual Ability and no Physics. The OAT is taken for optometry school admission and the DAT for dental school. Both share the Survey of the Natural Sciences, Reading Comprehension and Quantitative Reasoning, so much of the science prep overlaps.
Can I use my own class notes to make OAT questions?
Yes, and it is one of the most effective ways to study the science and physics sections. Upload your biology, chemistry, organic chemistry or physics notes or a review chapter, and the AI writes fresh multiple choice questions from that exact material with an answer key and explanations. A wrong answer points straight back to the topic to review.
Is this an official OAT practice test?
No. PDFQuiz is an independent study tool and is not affiliated with or endorsed by the American Dental Association, which administers the OAT. This tool generates practice questions from the material you upload so you can rehearse recall across the OAT content, and it does not reproduce real OAT questions. Use it alongside official ADA materials, not as a replacement.
