⭐⭐⭐☆☆
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.”
