Final Preparation and Exam Day

The final week before your Edexcel Chemistry exams is not the time for learning new material. It is the time for consolidation, confidence-building, and practical preparation.

The Final Week

Focus on Weak Topics Under Timed Conditions

Choose your 3–5 weakest topics (from your traffic-light checklist) and do targeted questions on each. Time yourself strictly — you need to practise answering under pressure, not just answering correctly.

Review Key Equations and Definitions

Make sure you can write from memory:

• q = mcΔT and ΔH = -q/n
• pH = -log[H⁺], [H⁺] = √(Ka × c)
• Rate = k[A]^m[B]^n
• Kc and Kp expressions
• ΔG = ΔH - TΔS
• pV = nRT (ideal gas equation)

Practise One Full Past Paper Under Timed Conditions

Do this early in the final week so you have time to address any issues that arise. Mark it honestly and note your final areas of weakness.

Review Mechanisms

Draw every organic mechanism from memory one final time:

• Free radical substitution
• Electrophilic addition
• Nucleophilic substitution (SN1 and SN2)
• Nucleophilic addition (to C=O)
• Elimination
• Esterification
