The perfect score is 150 points.

AIME Qualification & Cutoffs

To move on to the AIME you need to hit the yearly cutoff. 2024 official cut-offs:

• The AMC 10A cutoff: 94.5
• The AMC 10B cutoff: 105

👉 Tip: Even if the test feels tough, don’t give up mid-exam. Cutoffs often drop in harder years.

From AIME to USAJMO

Your AMC 10 score combined with your AIME score determines your USAJMO index.

USAJMO Index = AMC 10 Score + (10 × AIME Score)

Below are the USAJMO index thresholds for 2025:

Example: score 110 on the AMC 10 and 12 on AIME I → index = 230, comfortably past the recent USAJMO threshold.
