Upload the chapter and answer questions on it. Reading a textbook feels like studying right up to the moment somebody asks you what was in it.

It covers the body of the chapter rather than the summary box, so the questions reach the material the summary leaves out.
Sit the questions, see which parts of the chapter did not stick, and drill those again without spending another generation.

Substitution at a tertiary carbon proceeds through a carbocation, so the rate depends only on the substrate and racemisation follows. A primary carbon is approached from behind by the nucleophile in a single concerted step, inverting the stereocentre.

Why does substitution at a tertiary carbon give a racemic mixture of products?
A reaction rate doubles when nucleophile concentration doubles. Which mechanism is operating?
The concerted route is second order, so its rate depends on the nucleophile as well as the substrate. The carbocation route is first order and would be unchanged by that doubling.
What stereochemical outcome follows from backside attack at a primary carbon?
The nucleophile arrives opposite the leaving group, so the stereocentre inverts. This is the detail a chapter summary tends to state without explaining the geometry behind it.
The five you missed come back on their own as a shorter round, and redrilling them spends no part of your allowance.
The scored quiz needs no paid plan and never has. Student and Genius widen a chapter to 30 questions and add flashcards and written recall, all over the same Free-tier quiz.
Summary boxes are what everyone revises and what everyone else has also revised. The questions here come from the argument in the body, which is where the harder marks live.
Upload the same book again and GeniusPal recognises the text and carries on into the next stretch of it, so a term of reading moves forward rather than looping.
Getting through a chapter and knowing a chapter are different achievements, and only one of them is examinable. A score separates them in about four minutes.
A commercial question bank is written against the subject. These questions can only be about the chapter you uploaded, which is the one your reading list actually set.

A chapter at a time is the shape this is built for, and the enforced ceiling is 10 MB, which a typical chapter sits comfortably under. Whole textbooks usually exceed that, so split the file and upload the section you are actually being examined on this month. That constraint is less limiting than it sounds, because one 10-question set could not cover four hundred pages usefully anyway: it would sample so thinly that the questions felt random. Working a chapter at a time also matches how reading lists are set. If you do upload the same file again later, nothing is wasted, since GeniusPal identifies the material by its text and continues into the next stretch of it rather than regenerating questions about the opening pages you have already been tested on.
No, and avoiding exactly that is part of the point. Summary boxes are the most quoted and least discriminating part of any chapter: everyone revises them, so knowing them puts you level with the cohort rather than ahead of it. The reader works through the body of the chapter, which is where the mechanisms are explained, the exceptions are stated, and the worked reasoning lives. Those are the parts that separate a good answer from an adequate one under exam conditions. In practice this means some questions will feel harder than the ones at the end of the chapter, because end-of-chapter questions are usually written to confirm you read it while these are written to find out whether you followed it. Getting a lower score than you expected is the tool working.
Only if the file has a genuine text layer behind it. A publisher PDF almost always does, and so does anything exported from a modern e-reader, so those upload and read normally. A photograph of a page taken on your phone, or an old library scanner output, is an image with no characters in it at all. There is no optical character recognition here, so instead of guessing at letter shapes GeniusPal tells you the file carries no readable text and stops rather than producing a chapter quiz about a document it never read. If a scan is the only copy you have, run it through a free OCR tool first and upload the searchable PDF it returns. Typing or pasting a few key paragraphs into the box also works and takes less time than it sounds.
Scored multiple choice sits on every tier including the free one, so cost is a question about volume rather than features. A Free account covers 2 chapters, each producing a full marked test with explanations and unlimited redrills of what you missed, and no payment card is involved. Because those 2 are granted for the life of the account and never renew, a reading list of a dozen chapters is where a plan becomes the sensible option. Student is $14.99 monthly for 100 generations, and Genius asks $59.99 annually with a fair-use ceiling of 1000 each month. Paid tiers also take a chapter to 30 questions across proportionally more of its pages, which matters here more than on shorter material, since a dense chapter has far more testable content than a ten-question set can reach in one pass.
