GCSE Chemistry vs A-level Chemistry: which exam is right for you?
GCSE Chemistry covers atomic structure, bonding, quantitative chemistry, reactions and organic basics. A-level Chemistry splits into physical, inorganic and organic chemistry, with much more maths (equilibrium constants, kinetics, energetics) and reaction mechanisms. A strong grade in GCSE Chemistry or Combined Science and confident GCSE maths make the jump easier.

FAQ
What is the difference between GCSE Chemistry and A-level Chemistry?
GCSE Chemistry covers atomic structure, bonding, quantitative chemistry, reactions and organic basics. A-level Chemistry splits into physical, inorganic and organic chemistry, with much more maths (equilibrium constants, kinetics, energetics) and reaction mechanisms. A strong grade in GCSE Chemistry or Combined Science and confident GCSE maths make the jump easier.
Which is harder, GCSE Chemistry or A-level Chemistry?
GCSE Chemistry: aqa: 2 written papers, 100 marks each (200 marks in total), foundation or higher tier in 3 hours 30 minutes in total (2 × 1 hour 45 minutes). A-level Chemistry: aqa: 3 written papers of 105, 105 and 90 marks (300 marks in total) in 6 hours in total (3 × 2 hours). The longer exam covers more ground, but the harder one is the one further from your daily work. Take both free practice tests to see where you stand.
Can I hold both GCSE Chemistry and A-level Chemistry?
Yes. Most students take several subjects in the same exam series, and the timetable is built so the papers don't clash. Our plans are per subject, so add the subjects you need.
How do I prepare for GCSE Chemistry and A-level Chemistry?
Start with the free practice test for each, then study by topic. Premium is per exam (£29 a month each), so most people start with the exam they'll sit first and add the second when they're ready.
