How to Score Higher on AP Biology
Multiple Choice
- Eliminate obviously wrong answers first
- Pay attention to data tables and graphs - most questions require interpretation
- Know your key processes: photosynthesis, cellular respiration, DNA replication
- Practice reading experimental setups quickly
Long FRQs
- Answer every part of the question - each sub-part has separate points
- Use specific biological terms and vocabulary
- When explaining experiments, include hypothesis, variables, and controls
- Draw and label diagrams when they help explain your answer
Short FRQs
- Be concise but complete - no lengthy explanations needed
- Focus on the specific concept being asked about
- Use data from provided figures to support answers
- Practice interpreting graphs and applying math to biology
Reading tips helps. Writing a timed response helps more.
