Study Tips

1. Master evaluation metrics - Learn relevance, factual accuracy, consistency, fluency, and how to measure each for GenAI applications.

2. Understand LLM-as-a-Judge - Using one LLM to evaluate another is a powerful evaluation pattern. Learn implementation and limitations.

3. Practice troubleshooting - Hands-on experience with common GenAI failures: context overflow, hallucinations, poor retrieval, prompt confusion.

4. Learn A/B testing - Systematic model comparison requires proper experimental design, statistical significance, and business metrics.

5. Study agent evaluation - Agents add complexity. Learn to evaluate task completion rates, tool usage effectiveness, and reasoning quality.
