Bouncing Back: A Strategic Guide to Retaking A-Level Chemistry

Pardeep is a Head of Science, Head of Chemistry and A-Level Chemistry Examiner with a First-Class Master's degree from Imperial College London, over 15 years of teaching and tutoring experience. He has examined for CAIE, OCR and Edexcel and has a proven track record of delivering grade improvements of up to three grades.

 Here, he shares his practical guide to rebuilding after a failed A-Level Chemistry result, and making the retake count.

How to Approach an A-Level Chemistry Retake

By Pardeep | Head of Chemistry and A-Level Examiner | Sherpa Tutor

Receiving a failing grade on Results Day is a heavy blow, and it is entirely normal to feel disappointed, frustrated, or even a little lost right now. Take a breath and give yourself a moment to process it.

Once the dust settles, it is crucial to remember one thing: A-Level Chemistry is widely considered one of the most academically demanding subjects you can take.

A failing grade does not mean you are incapable of understanding the material; it almost always means there was a mismatch between your preparation strategy and the demands of the exam.

A retake year is a clean slate and a powerful opportunity. Here is how to rebuild your foundation and tackle A-Level Chemistry the second time around.

1. Conduct a Brutally Honest Post-mortem

Before you open a single textbook, you need to understand exactly what went wrong. 

• Did you run out of time? 
• Did the maths questions throw you? 
• Were the organic synthesis pathways a blur?



Request your exam scripts 

This is the most valuable diagnostic tool you have. Go through your papers with your teacher, otherwise an online tutor can help you understand what happened and how to get around it.

Identify the gaps 

Categorise your lost marks into three buckets: 

• Knowledge Gaps: eg. I didn't know the fact
• Application Errors: eg. I knew the fact but couldn't apply it to the scenario
• Exam Technique: eg. I misread the question or lost track of time

2. Overhaul Your Study Strategy

If you study the exact same way you did last year, you will likely get the same result. 

Reading the textbook and making pretty, highlighted notes is passive learning, and it will not survive the heat of an A-Level Chemistry exam.

Embrace Active Recall 

Test yourself constantly. Use flashcards for key definitions, transition metal colours, and standard conditions.

Focus on Understanding, Not Memorising 

A-Level mark schemes heavily penalise rote memorisation when it's applied to the wrong context. You need to understand why a reaction happens, not just that it happens.

3. Attack the Traditional Stumbling Blocks

Having guided many students through successful chemistry retakes, I see the same three areas cause the most trouble:

The Mathematics

Chemistry is applied maths. Strengthen your quantitative skills with focused practice or a refresher in A-Level Maths.

Organic Synthesis Mapping

Don't view organic reactions as isolated events.

Descriptive Physical Chemistry

Topics like lattice enthalpy or buffer solutions require precise language.

4. Become Obsessed with Examiners' Reports

Past papers are essential, but the examiners' reports are your secret weapon.

With a strategic approach and a willingness to adapt, you can absolutely turn that grade around - and with Sherpa, you can always find me for support.
