📊 Difficulty & Insights

🎯 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.”
