Why this topic matters

Parents and students often underestimate how much IGCSE and A-level subject choices can expand or limit future options for Computer Science and Software Engineering. 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

• Mathematics (Extended).
• Computer Science if offered.

Strong additional IGCSE subjects

• Physics and Additional Mathematics for mathematically strong students.

Recommended International A-level subjects

Core / required A-levels

• A-level Mathematics – required by most serious CS programmes.

Strong A-level combinations

• A-level Computer Science strongly recommended.
• Further Maths for highly selective courses.
• One more rigorous subject such as Physics or Economics.

Common mistakes and edge cases

• Universities often accept applicants without A-level CS if Maths is strong, but programming experience is still expected through projects and competitions.
