DCS RankWhat it is
Marks tell you what happened. Student DNA tells you why. Instead of one score, it tracks the five traits that actually move your rank and shows how they're trending — so you stop guessing what to fix.

What this reveals
Your weak point isn't Biology. Your real bottleneck is retention decay.
Recovery is strong (81) — you bounce back after a bad day. But decay resistance (52) means concepts fade before mocks. The plan should shift toward spaced revision, not more new chapters.
How it works
1
Every attempt logged
Mocks, practice and timed sets feed the engine — right/wrong, speed, confidence.
2
Five traits scored
Speed, accuracy, recovery, decay resistance and confidence are computed and normalised.
3
Bottleneck found
The lowest-leverage trait — the one capping your rank — is surfaced in plain language.
4
Plan adapts
Your study plan re-weights toward the trait that will move your rank the most.
What you get
✓A clear answer to: what should I actually fix next?
✓Trends over time, so you see traits improving — not just one score
✓Decay and recovery signals most apps ignore entirely
✓A plan that targets your bottleneck, not your fear
