Practice discrete questions built from your own material

Printed or downloadable MCAT discrete practice questions are easy to find, but they rarely match the content you are reviewing this week. A generated set built from your own notes keeps your practice focused on what you are actually studying.

Multiple-choice, true/false and short-answer questions from your own notes
Explanations that show why the correct answer is right
Study in the browser on the free plan, with exports on paid plans
Spaced repetition on Plus so missed questions come back on schedule

Example MCAT discrete practice questions by science topic

Which amino acid side chain is most likely to form a salt bridge with the carboxylate of an aspartate residue at pH 7.4?Lysine. Its epsilon-amino group is protonated at physiological pH, so it carries a positive charge that pairs with the negative carboxylate.

True or false: adding more enzyme to a reaction lowers its activation energy.False. Enzymes lower activation energy, but adding more enzyme changes the reaction rate without changing the activation energy or the equilibrium position.

In eukaryotic cells, where do the enzymes of the citric acid cycle reside?The mitochondrial matrix. Succinate dehydrogenase is the exception, because it is embedded in the inner mitochondrial membrane.

At constant temperature, a gas has its volume halved. What happens to its pressure?It doubles. Boyle's law states that pressure and volume are inversely proportional when the amount of gas and the temperature are fixed.

Why does a stronger acid have a weaker conjugate base?A stronger acid releases its proton more readily, so its conjugate base holds the proton less tightly and is a weaker base.

Generate the full set

Questions from your own material

Upload the review sheets, lecture slides or textbook chapters you are working through, and get standalone questions drawn from them.

Explanations for every answer

Each question comes with a short explanation of why the correct choice is right, so a missed item teaches you something.

Export when you need it

Plus exports to PDF and DOCX. Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a page. Photos are read with text recognition.

Choose a question type

Pick multiple-choice, true/false or short answer, then generate a set covering the topics in your material.

Practice and review misses

Work through the questions, read the explanations for anything you got wrong, and return to those items later.

Discrete questions stand alone without a shared passage, so each item has to be answered on its own terms. Generating them from your own sources helps you cover biology, biochemistry, chemistry, physics and behavioral science topics in the order your course or review plan requires.

Pair each set with the explanations. Sorting your misses by content category shows which subjects need another pass before exam day.

Frequently asked questions

How should I review discrete questions on the MCAT?

Sort your missed questions by content category and note whether each miss came from a knowledge gap or a reasoning error. Revisit the underlying concept before doing more questions on that topic.

How many discrete questions should I do each day?

There is no single right number. Choose a daily set you can finish and review thoroughly, and keep it consistent over several weeks.

Can I export generated questions to Moodle or QTI?

Yes. QTI 2.1 and Moodle XML export are included on the Pro plan at $14.99 per month, and PDF and DOCX export are included on Plus.

Is there a free plan, and do students get a discount?

The free plan includes 3 generations per month and browser study, and no credit card is needed to start. Students with a school email get 40 percent off paid plans.
