## Guidance

### Parent advice

AMC 12 B is a second sitting at the same level as AMC 12 A. Each attempt is scored independently; qualifying on either is enough for AIME.

### Student advice

On AMC 12 B day, AMC 10 B runs at the same time — you must choose one level.

### Teacher advice

B papers are not harder than A — just different questions with separate score distributions.

## How to prepare

- Work through past AMC 12 B papers specifically
- Review mistakes from AMC 12 A before attempting B
