Stop guessing what to study next.
Answer one question below. See what Elio picks next, and why.
Try a questionSample
At pH 7.4, which amino acid side chain carries a negative charge?
How sure are you?
Next upSample
Amino acid side chains
Chosen because of this attempt:
- Side-chain charge at pH 7.4, missed with high confidence
Misses you were sure about come back first, as a retry. A retry never clears a topic. A new question on the same idea does.
Aspartate is right. Its side chain has a pKₐ near 3.9, so at pH 7.4 it has lost its proton and carries a negative charge.

Today
Today names one next set, how long it should take, and the attempts that chose it.
Calendar
Calendar lays out your plan from now to your exam date, one day at a time. Each day opens straight into its sets.
Review
Review brings back the cards you have actually met, scheduled from your own results rather than a fixed timetable.
Progress
Progress shows a readiness estimate with its uncertainty. When the evidence is thin, it says so and names what would settle it.

No score promises. No streaks.
Elio will not print a score it cannot support. Readiness is an estimate with its uncertainty shown, and when the evidence is thin it says so instead of guessing. It does not count streaks or reward you for opening the app. It does not guarantee any score or admission outcome, and it is not affiliated with or endorsed by the AAMC. Your study record is yours, and you can export it at any time.
$12 per month, or $79 for a 120-day exam cycle that does not renew. Both unlock the same app. See pricing
