You already own a shelf of content review. What you do not own is a way to find out whether chapter nine went in, without spending a full-length on finding out.

The books you bought and have been reading passively. Upload a chapter and answer questions on it in four minutes instead of rereading it in forty.
Undergraduate biochemistry and physiology notes cover much of the content sections, and they are already in your own words.
The explanations you wrote after a practice block are the highest-value text you own. Paste them in and be asked about them again a fortnight later.
A paragraph from a chemistry review chapter, and the marked paper that comes back from it. Sample material, written by us to show the shape of the output.
Your review chapter
General chemistry review, acid-base chapter
A buffer resists pH change most effectively when the concentrations of weak acid and conjugate base are equal, which occurs when pH equals pKa. Buffering capacity falls away rapidly more than one pH unit from that point.

3 of the 10 questions
At what pH is a buffer system at its maximum capacity?
A buffer is prepared two pH units above its pKa. What has happened to its capacity?
Why does equal concentration of acid and conjugate base maximise resistance to pH change?
Either added acid or added base can be absorbed by a substantial reserve of the opposite species. Once one component dominates, the reserve of the other is small and additions in that direction move the pH sharply.
The three you missed come back on their own as a shorter round, and redrilling them spends no part of your allowance.
The scored quiz shown here runs on every plan, Free included, and each of the Free plan's 2 generations produces a complete one.

Not from a general model of your subject. Only from the document in front of it, which is what makes the questions match your module.
Questions you get wrong join a weak pile and return in the daily review. Mastery lapses after a fortnight, so nothing stays finished forever.
No, and using it as one would be a mistake worth avoiding. Official practice material and the established third-party banks are written against the real blueprint, use genuine passage structures, and are calibrated for difficulty, and none of that is true here. What this addresses is the layer underneath them, which is whether you actually retained the content you reviewed. Most people burn expensive practice questions discovering that they never learned amino acid properties, when a four-minute quiz on their own review chapter would have told them the same thing for nothing. Use this to confirm content retention between review sessions, and save the banks for practising the reasoning and timing that only realistic passages can teach. They solve different problems and the cheap one should come first, because a bank block spent proving you did not learn something is a block you cannot spend twice.
Content review chapters are the obvious starting point and the highest yield, because they are dense, text-based, and the thing you are most likely to be reading passively. Upload one chapter at a time rather than a whole book, since one set of questions spread over four hundred pages samples far too thinly to test any of it. Your undergraduate biochemistry and physiology notes work well and are already in your own words. The most underrated upload is your error log: the explanations you wrote after a practice block are precisely the material you most need to retain and almost never revisit. What will not work is a photographed page or a scanned book, since neither carries a text layer that can be read, and anything whose substance is a diagram rather than prose.
Not in the way the exam means it. The real test presents an unfamiliar research passage and asks questions that depend on reasoning within it under time pressure, and that format is the central skill it assesses. What you get here is a set of 10 standalone multiple-choice questions drawn from the document you uploaded, which tests whether you know the content rather than whether you can reason through new material quickly. That is a genuine and useful thing to test, and it is not the same thing. On a paid plan the written-recall mode gets closer to exam pressure in one respect, because you produce an answer from an empty box rather than recognising it among four options, but it still is not passage reasoning and nothing here claims to be.
