Analyze Your Score Report

Focus on Weak Areas (80/20 Rule)
Spend 80% of your study time on the 2-3 domains where you scored lowest. You probably already know the topics you scored well on. For AWS Certified Machine Learning Engineer - Associate (MLA-C01), this targeted approach is far more effective than re-studying everything.

- Domain 1 (data preparation) is the largest block at 28 percent, so drill Glue, Data Wrangler, and Feature Store
- Learn when to pick real-time, serverless, asynchronous, and batch SageMaker inference; the tradeoff shows up repeatedly
- MLA-C02 registration opens September 1, 2026, and the last English MLA-C01 sitting is September 28, 2026
