MCAT practice questions from textbook: convert the books you already own.

You can upload it for your own private studying, but read AAMC's terms before redistributing anything that comes out. The bigger win is the AAMC-style practice you cannot buy: passage-format vignettes generated against your Kaplan or Princeton Review chapters, the chapters from your undergrad textbook, or the lecture handouts from your post-bacc. Those are the gaps the official AAMC packs do not cover.

Yes, because passage format is one of the four output formats. The MCAT science sections are short passages followed by 4 to 6 questions that ask you to apply information from the passage plus outside knowledge. Studyly's case-style format produces exactly that shape: a 200 to 400 word passage drawn from your chapter, followed by questions that test interpretation, application, and reasoning rather than flat recall. You also get flat MCQs alongside, for when you just want recognition reps on definitions.

Single chapters, full textbooks, or a folder of mixed sources all work. A 200-page Kaplan biology book and a 90-page lecture handout get treated the same way: parsed into sections, then turned into about 200 questions across the four formats. If you have the full Kaplan 7-book set, upload one book at a time so each set of questions stays organized around a subject. Each upload grows its own tree on the dashboard, which is how you keep biology questions separated from physics questions when exam day arrives.

Studyly scored 81.3 on a held-out three-document evaluation rubric covering factual correctness, clarity, distractor quality, and question-type coverage. The same eval scored Unattle at 78.0, Gauntlet at 68.0, and Turbolearn at 57.8. For MCAT specifically, factual correctness and distractor quality are the two scores that matter most: a wrong keyed answer teaches you the wrong concept, and a too-obvious distractor inflates your perceived accuracy. Methodology and per-criterion scores are at studyly.io/quality.

Three things break when you do that. ChatGPT will write questions, but it has no quality rubric, so a wrong keyed answer reads identical to a right one. It does not track which topics you got wrong, so you re-drill what you already know. And it serves the same wording every time, so within a few passes you pattern-match the question instead of the biology. Studyly's auto-rephrase rewrites each question on revisit, and the spaced repetition engine weights revisits toward what you missed, so the second pass is a real retrieval and not a recognition test.

Those route to the image-occlusion format. Studyly takes the diagrams in your PDF, including amino acid R-group tables, nephron cross-sections, glycolysis pathways, the eye and ear cross-sections, and generates flashcards where one part of the diagram is masked. You name the masked region, then reveal. The same cards export to an Anki .apkg with occlusion masks intact if you already live in Anki for the rest of your studying.

No, and it is not meant to. UWorld and the AAMC practice tests are the calibration tools for predicting your score, and you should still do all of them in the last six to eight weeks. The gap they do not fill is the content-review phase: when you are reading through Kaplan Chapter 4 of biology and want practice questions on that exact chapter to make sure you actually retained it. That is what this is for. The two stacks work together: textbook-derived practice during content review, official packs and UWorld during the dedicated phase.
