Are the exams calibrated to real difficulty?

Yes. Question difficulty is calibrated using Bloom's taxonomy tags — recall, apply, analyze, evaluate. You can pick a mix, and the default mirrors typical undergraduate exam profiles (60% recall/apply, 40% analyze/evaluate).

Can I retake an exam?

You can retake any exam unlimited times. Each retake regenerates questions from the same sources, so you're not memorizing the form — you're testing your actual mastery of the underlying material.

Does it support essay / free-response questions?

Yes — short-answer and free-response are supported. Grading is assisted by Revu (keyword matching + structural check) with your final call on partial credit.

What's in the results breakdown?

Per-section accuracy, time-per-question, confidence vs. correctness (a dangerous-confidence map), and flagged cards. Everything you missed auto-enrolls in tomorrow's warm-up.

Is there a timed mode?

Yes. Timed, untimed, or paced (a soft timer per question). You can also lock the question nav to simulate strict exam conditions.

Why it works

Practice is prediction, not memorization.

The strongest predictor of exam performance is practice-exam performance. Revu makes that loop tight and data-rich.

Real-conditions practice

Timed, paced, or untimed. Simulate exam conditions at will, across unlimited retakes.

Weakness targeting

Retakes can be restricted to your weak sections. Every minute on the exam is productive.

Calibration map

See where your confidence was miscalibrated — the worst answers are sure-and-wrong.

Fresh questions every run

Each retake generates new questions from the same sources. You're testing mastery, not memorization.

Feedback loop to FSRS

Misses flow into your spaced repetition state. Tomorrow's session reflects today's exam.

Auto-save + recovery

Browser crash? Connection drop? In-progress exams are recovered seamlessly.

Frequently asked
