Take the test before the test

The worst place to find a gap is in the exam room. Build a practice exam from your own sets and notes, take it under real conditions, and check your work against a model answer for every question — while there’s still time to fix what you missed.

The first attempt shouldn’t be the real one.

Practice exam
In glycolysis, what does hexokinase do?
Hexokinase adds a phosphate to glucose, releasing energy to start the pathway.
Model answer: hexokinase adds a phosphate to glucose — that step uses energy, it doesn’t release it. How’d yours line up?

How it works

  1. 1
    Point it at your material

    Pick a set or your notes — the exam is built from what you actually have to know.

  2. 2
    Take it like the real thing

    Multiple choice and short answers, on a timer if you want the pressure.

  3. 3
    Check against the model answer

    Multiple choice grades itself. For short answers you get a model answer and explanation to check your own against — so the retake targets the gap, not the whole chapter.

What you get

  • Multiple-choice and short-answer questions from your own sets and notes
  • Instant grading on multiple choice; a model answer and explanation on every short answer
  • Wrong answers written to catch real confusions, not filler
  • Timed mode when you want exam pressure
  • Results that show which topics to review next
  • Retake as many times as you want — it’s practice

Questions

Is this cheating?

No — practicing on material you’re allowed to study is what studying is. Uploading a live or leaked exam is a different thing entirely, and it’s against our rules and your school’s. Our honor code spells out the line. Read the honor code →

Where do the questions come from?

From your own sets and notes. The AI writes multiple-choice and short-answer questions from the material you give it — nothing scraped, nothing from other students.

How does the grading work?

Multiple choice is graded instantly. For short answers you get a model answer and an explanation, and you mark yourself right or wrong against it — an honest self-check is what makes the retake count.

When should I take one?

Earlier than feels natural. A practice exam a week out shows you what to review while there’s still time to fix it — the night-before run is a confidence check, not a study plan.

The first attempt shouldn’t be the real one.
