Practicing MCAT content one topic at a time

Drilling one content area until it sticks keeps MCAT prep organized, and mcat practice questions by topic make that possible when the questions come from the material you are actually studying. DeckOwl does not sell a ready-made question bank. It builds sets from the notes, slides or textbook chapters you already have.

Keep each set limited to one topic so misses point to a specific gap.
Read the explanation even for questions you answered correctly.
Retry missed questions after a day or two instead of repeating them right away.
Check generated answers against your course material before relying on them.

Example MCAT biology and biochemistry practice questions by topic

Which organelle is the primary site of oxidative phosphorylation in eukaryotic cells?The inner mitochondrial membrane. The electron transport chain and ATP synthase are embedded there, which builds the proton gradient across it.

True or false: Enzymes lower the activation energy of a reaction and change its equilibrium constant.False. Enzymes lower activation energy and speed up the reaction, but they do not change the equilibrium constant or the overall free energy change.

Why does a competitive inhibitor increase the apparent Km of an enzyme without changing Vmax?It competes with substrate for the active site, so more substrate is needed to reach half-maximal velocity, while very high substrate concentrations can still reach the same Vmax.

In a cross of two heterozygotes (Aa × Aa), what fraction of offspring are homozygous recessive?One quarter. Only aa offspring show the recessive phenotype, and that genotype appears in 1 of the 4 Punnett square boxes.

Which amino acid side chains are positively charged at physiological pH?Lysine and arginine. Their side chains are protonated near pH 7.4, which makes them basic residues.

Generate the full set

Questions grouped by topic

Each generation uses only the material you upload, so a set on amino acids stays separate from your enzyme kinetics or genetics notes.

Explanations for every answer

Multiple-choice, true/false and short-answer questions each come with an explanation of why the correct answer is right and the others are not.

Export when you need it

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

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file or photos of pages. Photos are read with text recognition.

Generate one topic at a time

Split your material into sections such as biochemistry, physics or psychology and generate a separate question set for each.

Practice and review

Answer in your browser, read each explanation, and return to missed topics later. The free plan includes 3 generations per month.

Working by topic shows you where a gap is. If every missed question in a set involves the same concept, you know which section of your notes to review before moving on. Generating a fresh set from that section later gives you a new check on the same idea.

Frequently asked questions

How many MCAT practice questions should I do per topic?

There is no fixed number that works for everyone. Aim for enough questions to see whether you miss the same idea more than once, and review each explanation before starting the next set.

How do I study MCAT topics I keep getting wrong?

Generate questions from only that section of your notes, then retry them after a day or two. Spaced review usually works better than repeating the same set in one sitting.

Can I export MCAT questions to Anki or PDF?

Yes, on paid plans. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML.

Do I need a credit card to try it?

No. The free plan includes 3 generations per month and studying in the browser, and you can upgrade later if you need more.
