How to practice for Biology
- Expect questions built on data, diagrams and experiments. Practice reading a graph and stating the claim it supports, not just recalling facts.
- On free-response, answer exactly what the task verb asks (identify, describe, explain, justify, predict). Each verb asks for a different depth.
- Grade your long and short FRQs with the released scoring guidelines and sample responses to see how much detail earns a point.
Then grade what you wrote (how to grade your own FRQs) and log what you miss (turn missed questions into a study plan).
