Overview

Start with the course, not the subject list
| Target path | Usually essential | Often valued | Rarely required | |-------------|-------------------|--------------|-----------------| | STEM (engineering, CS) | Maths (9709), often Further Maths (9231) | Physics (9702), CS (9618) | Fourth science | | Medicine / dentistry | Chemistry (9701), Biology (9700) | Maths or Physics | Psychology alone | | Economics / finance | Maths (9709) | Economics (9708) | Business without Maths | | Law | Any two “facilitating” subjects | History (9489), English | Law A-Level (9084) not required for UK law |
