-
Short FRQs: Included rate law from experimental data, net ionic equations, and explanation of molecular structure with hybridization
📊 Difficulty & Insights
| Section | Difficulty | Comments |
|---|---|---|
| Multiple Choice | ⭐⭐⭐☆☆ | Mostly manageable, but graphs and lab setups challenged quick readers |
| Free Response | ⭐⭐⭐⭐☆ | Success required clear structure, unit-aware math, and correct setup explanations |
🎯 Prep Tips for 2025
- Focus on lab-based thinking: titrations, buffers, particulate diagrams
- Drill ICE tables for weak acid/base and K expressions
- Review thermo explanations in full sentences — not just math
- Memorize equation sheet content but more importantly — know when to apply it
“The 2024 Chem paper rewarded students who could do more than solve — they had to explain like chemists.”
