Why this topic matters

Parents and students often underestimate how much IGCSE and A-level subject choices can expand or limit future options for Data Science, Artificial Intelligence and Statistics. 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) with top grades.

Strong additional IGCSE subjects

• Additional Mathematics, Computer Science and Physics.

Recommended International A-level subjects

Core / required A-levels

• A-level Mathematics.

Strong A-level combinations

• Further Mathematics A-level strongly preferred for the most mathematical courses.
• At least one from Computer Science, Physics, Economics.

Common mistakes and edge cases

• Even degrees marketed as “Data Science” are maths-heavy; students should be comfortable with calculus and probability by the end of sixth form.
