Introduction
Why These Questions Keep Coming Up
If you look at five years of Edexcel Chemistry A-Level past papers, something becomes very clear:
the same ideas keep appearing in different disguises. The wording changes, the numbers change,
but the underlying concept being tested stays the same. This guide cuts through the noise. It
identifies those repeat-offender topics, shows you the exact thought process the mark scheme
rewards, and gives you the language that examiners want to see.
Working through these questions is not about memorising answers. It is about recognising the
question type within the first few seconds, then knowing exactly which steps to take. That skill is
worth far more than any single fact you could learn off by heart.
>> This guide covers Paper 1, Paper 2, and Paper 3 question styles.
How to Use This Guide
-> Read the question carefully -- identify the command word (describe, explain, calculate, evaluate).
-> Check how many marks are available. Each mark usually needs a separate, distinct point.
-> Use the model answers as templates, then practise writing your own without looking.
-> Pay special attention to the Examiner Tips -- this is where most marks are lost.
Command Word What It Means Marks Approach
Describe State what happens -- no explanation needed One point per mark
Explain Give the reason why something happens Cause + effect per mark
Calculate Show working, give units, round correctly Method + answer marks
Evaluate Weigh up evidence, give a judgement Both sides + conclusion
Suggest Apply knowledge to unfamiliar situation Any valid scientific reason
State Give a brief, direct answer One fact per mark
