A-Level Chemistry – The Best Ways to Learn and Then Revise

A-Level Chemistry has a reputation—and not always a friendly one.

Students often say:

“I understand it in class… but I can’t answer the questions.”

That’s the key problem. Chemistry isn’t just about learning—it’s about applying.

After 40+ years of teaching, I’ve found that success in A-Level Chemistry comes down to doing two things properly:

Learning the content the right way
Revising in a way that matches the exam

Let’s break that down.

Step 1: Learning Chemistry Properly (Not Just Copying Notes)

The biggest mistake students make is passive learning.

Reading notes ≠ learning
Highlighting ≠ understanding
Watching videos ≠ mastery

What actually works:

1. Build understanding first

Ask: Why does this happen?
Link topics together (e.g. bonding → structure → properties)
Use diagrams wherever possible

2. Learn definitions precisely
Exam boards love definitions—and they are picky.

For example:

Not “energy needed to break a bond”
But: “the enthalpy change required to break one mole of bonds in the gaseous state”

That level of precision matters.

3. Do examples immediately
After learning a concept:

Do 2–3 questions straight away
If you can’t do them → you haven’t learnt it yet

Step 2: The Power of Practice (This Is Where Grades Are Won)

Chemistry is a skills subject.

You wouldn’t learn to sail (or drive a powerboat!) just by reading about it—you have to do it.

Same here.

Focus on:

Past paper questions by topic
Repeating question types (they do come back)
Learning mark scheme language

Step 3: How to Revise Effectively

Revision is not re-learning everything from scratch.

It is:

Training your brain to recognise and solve exam questions quickly and accurately

The 3-Step Revision Cycle

1. Recall

Blurting (write everything you remember)
Flashcards
Quick quizzes

2. Apply

Exam questions
Timed practice
Mixed topics

3. Review

Mark your work properly
Add corrections to notes
Identify weak areas

Then repeat.

Step 4: Topic-by-Topic Strategy

Some topics need slightly different approaches:

Physical Chemistry

Practice calculations daily
Learn formulas AND when to use them
Show full working (marks are method-based)

Organic Chemistry

Learn mechanisms step-by-step
Practise drawing them repeatedly
Understand why electrons move

Inorganic Chemistry

Focus on patterns (trends in the periodic table)
Use colours, reactions, and observations
Link structure to behaviour

Step 5: The Final Weeks Before Exams

This is where many students go wrong.

They panic… and go back to reading notes.

Don’t.

Instead:

Do one full paper per day
Mark it properly
Redo mistakes the next day

This is the fastest way to improve grades.

Common Mistakes to Avoid

❌ Only reading notes
❌ Avoiding hard questions
❌ Not marking work properly
❌ Ignoring definitions
❌ Leaving revision too late

Final Thought

A-Level Chemistry isn’t about being “naturally good.”

It’s about:

Practising regularly
Learning from mistakes
Thinking like the examiner

Do that—and the grades will follow.
