Why this topic matters

Parents and students often underestimate how much IGCSE and A-level subject choices can expand or limit future options for Chemistry. Universities look first at which subjects you have taken, and only then at the grades. Getting this wrong can close doors even for very capable students.

Recommended IGCSE subjects

Essential IGCSE subjects

• IGCSE Chemistry and Mathematics (Extended).

Strong additional IGCSE subjects

• IGCSE Physics and Biology to keep related routes (e.g. Chemical Engineering, Biochemistry) open.

Recommended International A-level subjects

Core / required A-levels

• A-level Chemistry.

Strong A-level combinations

• Two from Maths, Physics, Biology depending on interests.

Common mistakes and edge cases

• Some pure Chemistry courses strongly prefer applicants who have also studied Maths at A-level.
