Common FRQ Mistakes in AP Biology

Introduction

• Presenter: Melanie King from The Absolute Recap
• Focus: Common mistakes in Free Response Questions (FRQ) in AP Biology exams
• Audience: AP Biology students

Key Mistakes to Avoid

1. Ignoring Error Bars

   • Purpose of Error Bars: Indicate data spread from the average.
   • Important Tip: If error bars overlap, conclude no statistical difference between groups.

2. Mislabeling Axis Scale

   • Issue: Incorrect placement can lead to misinterpretation.
   • Advice: Pay attention to data table scaling; avoid evenly spacing data points for visual symmetry.
   • Consequence: Can affect graphing accuracy and rate calculations.

3. Speaking in Generalities

   • Problem: Points can’t be awarded for vague statements.
   • Solution: Use specific terms from prompts and biology knowledge.
   • Example of Non-Specificity: "This one is more than that one."

4. Confusing Controls and Constants

   • Controls:
     • Can be positive or negative.
     • Serve as reference points for comparison.
   • Constants:
     • Consistent elements in all groups to ensure only the independent variable changes.
   • Common Confusion: Students often mix these up.

5. Overloading with "Science Vomit"

   • Mistake: Over-explaining or including unnecessary information doesn’t earn points.
   • Recommendation: Stick to the prompt, focus on task verbs, and keep answers concise.

Conclusion

• Recap of Tips:
  • Check error bars.
  • Scale graphs correctly.
  • Use specific terms.
  • Distinguish between controls and constants.
  • Focus on answering the prompt.
• Additional Resources: Podcast, study guides, and AP Biology Ultimate Review Packet with practice tests are available for further study.
