How to Score Higher on AP Chemistry
Multiple Choice
- Know your periodic trends cold - ionization energy, electronegativity, atomic radius
- Practice dimensional analysis and unit conversions
- Understand Le Chatelier's principle for equilibrium questions
- Review common reaction types: acid-base, redox, precipitation
Long FRQs
- Show all your work - partial credit is awarded for correct steps even with wrong final answers
- Include units in every calculation step
- For lab-based questions, explain your reasoning about experimental design and error analysis
- Practice drawing and interpreting particulate diagrams
Short FRQs
- Be direct and specific - each question targets one concept
- Use correct chemical notation and terminology
- For explanation questions, connect macroscopic observations to molecular-level reasoning
- Don't over-explain - concise, accurate answers score full points
Reading tips helps. Writing a timed response helps more.
