How to build a daily MCAT question habit

A useful set of MCAT practice questions of the day should match the content you are reviewing this week, not a generic bank.

Pull one or two topics from today's reading into each set.
Read the explanation even when you answer correctly.
Keep a running list of concepts you missed and retest them.
Mix in a few short-answer questions to practice explaining your reasoning.

Example MCAT biology and chemistry practice questions

Which step of the Krebs cycle directly produces a high-energy phosphate bond?Succinyl-CoA synthetase, which makes GTP. This is substrate-level phosphorylation, not oxidative phosphorylation.

True or false: adding a catalyst shifts the position of a reaction at equilibrium.False. A catalyst speeds the forward and reverse reactions equally, so the equilibrium position stays the same.

A competitive inhibitor is added to an enzyme reaction. How does it change Km and Vmax?Km increases and Vmax is unchanged. Enough substrate can outcompete the inhibitor for the active site.

Where is most filtered water reabsorbed in the nephron?The proximal convoluted tubule. Water follows the sodium reabsorbed there, so this reabsorption is isosmotic.

Which mechanoreceptor adapts rapidly and detects light touch in hairless skin?Meissner corpuscles. They are rapidly adapting receptors suited to detecting light touch and flutter.

Generate the full set

Questions from your material

Upload PDFs, slides, DOCX files, plain notes or photos of pages. Questions come from what you actually studied.

Explanations for every answer

Each multiple-choice, true/false or short-answer item explains why the right answer is right, so a miss becomes a lesson.

Exports when you need them

Study in the browser on the Free plan. Plus adds PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML.

How it works

Upload your material

Add a PDF, slides, DOCX, plain notes or a photo of a page.

Choose a question type

Pick multiple-choice, true/false or short answer, then generate a set.

Practice a set each day

Work through the questions, read every explanation, and repeat the topics you missed.

Printable, ready-made sets are common, but they cannot reflect your course or the chapter you just finished. DeckOwl builds a custom quiz from your own material, so each day you can test the organ systems, enzyme kinetics or behavioral science topics in front of you.

Write the concept behind each miss into your notes, then retest it a few days later. Spacing practice this way builds recall that holds up under exam conditions.

Frequently asked questions

How many MCAT practice questions should I do each day?

Most students find a short daily set more useful than a long session, especially when they read every explanation. Choose a number you can finish with time to review.

How do I study the questions I get wrong on the MCAT?

Note the concept behind each miss, reread that section of your notes, and retest it after a few days. Explaining why the correct choice fits will do more for you than memorizing the letter.

Can I export the questions for a course platform?

Yes, on paid plans. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML for course platforms.

Is there a free plan?

Yes. The Free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Students get 40% off with a school email.
