Lecture Notes: Tips for IGCSE Biology Paper 6

Introduction

• Focus on preparing for the IGCSE Biology Paper 6 exam.
• Presenter scored 95 in this paper and shares tips learned over two years.

Last-Minute Preparation Tips

• Mistake Book/Sheet:
  • Compile keywords, writing patterns, and common answers.
  • Essential for marking schemes; be very specific in answers.
• Consolidate Resources:
  • Gather all past mistakes, worksheets, notes into one booklet.
  • Identify patterns in common questions like experimental improvements (e.g., repeat experiments, average results).

Drawing Tables

• Structure:
  • Dependent variable within table boxes.
  • Independent variable on the left.
  • Avoid units in individual boxes; only use in headers.
• Materials:
  • Use pen (not pencil) for drawing tables.

Designing Experiments

• Answer Structure:
  • Include independent, dependent, and controlled variables.
  • Explain procedure/method clearly.
  • Mention and explain control group purpose.
  • Repeat experiments for accuracy.
  • Include safety precautions (e.g., gloves, goggles).
• Study Tip:
  • Create acronyms to remember answer structure.

Graphs

• Types of Graphs:
  • Line graphs for numerical data.
  • Bar charts for discontinuous data (gaps between bars).
  • Histograms for continuous data (no gaps).
• Graph Drawing Tips:
  • Use pencil for neat, crisp lines.
  • "DRY MIX" for axis orientation (Dependent on Y, Independent on X).
  • Label axes with units.
  • Extend lines to estimate points beyond given data.

Biomolecule Tests

• Know Tests:
  • DCPIP, Ethanol Emulsion, Benedict's, Starch/Iodine tests, etc.
• Sources of Error:
  • Frequently tested in Paper 6; review well.

Conclusion

• Recap of tips for high exam score.
