How should I rate? ▸
Got it — I knew the approach and wrote it without getting stuck
Struggled — Solved it, but had to think hard, check hints, or debug a lot
Needed solution — Couldn't solve it without looking at the answer
Rate based on what you did, not how you feel after seeing the answer. When in doubt and you solved it, pick Got it — the algorithm penalizes more than it rewards.
