Why build your own MCAT practice tests

Pre-made question banks rarely line up with the exact topics in your prep book or lecture notes. Upload those materials and DeckOwl builds an MCAT practice test hub from them, with questions drawn only from what you provided.

  • Questions match the topics in your own textbook and lecture slides
  • Multiple-choice, true/false and short-answer formats in one set
  • Explanations that show the reasoning behind each correct answer
  • Free plan includes 3 generations per month with browser study
Example MCAT practice questions with answers
Which hormone raises blood glucose by stimulating glycogenolysis and gluconeogenesis in the liver?Glucagon. It is released when blood sugar falls, while insulin works in the opposite direction to lower it.
Which organelle houses the enzymes of the citric acid cycle in eukaryotic cells?The mitochondrial matrix. Glycolysis, by contrast, takes place in the cytosol.
True or false: a competitive inhibitor changes the Vmax of an enzyme.False. It raises the apparent Km but leaves Vmax unchanged because enough substrate can outcompete it.
Which gas law states that pressure and volume are inversely related at constant temperature?Boyle's law. For a fixed amount of gas at constant temperature, compressing the gas raises its pressure in proportion.
Which brain structure coordinates balance and smooths fine motor movements?The cerebellum. It compares motor commands with sensory feedback to correct movement as it happens.

Questions from your own material

Multiple-choice, true/false and short-answer questions are built from the PDFs, slides, DOCX files or photos of pages you upload.

Explanations for every answer

Each question comes with an explanation, so a wrong answer becomes a short lesson on the concept you missed.

Study and export options

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

How it works

Upload your study material

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

Choose your question types

Pick multiple-choice, true/false or short-answer questions and generate a practice set from your content.

Take the test and review

Answer the questions, read each explanation, then retest the topics you missed so they stick.

Each set includes multiple-choice, true/false or short-answer questions with explanations, so you can see why an answer is right as well as which one you picked. Because the questions come from your own sources, your review stays focused on the material you actually have to learn.

Check any AI-generated question against your source before you rely on it, especially for dense passages and numerical problems.

Frequently asked questions

How should I use practice tests when studying for the MCAT?

Take a test under timed conditions, then sort the missed questions by content area and reread those sections. Retesting the same weak topics a few days later helps the material stay in memory.

How many questions should a practice session include?

Shorter timed blocks followed by a full review of every explanation tend to work better than long sets you rush through. Adjust the length to how much time you can give each session.

Can I export my practice tests to Anki or Moodle?

Anki export is included in the Plus plan, and QTI 2.1 and Moodle XML export are part of Pro. The free plan lets you study in the browser without exports.

Is there a free plan, and do I need a credit card?

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