Start with two or three possible directions
You do not need one final career at school. Group possibilities by the kind of work that interests you: understanding people, designing systems, working with numbers, building things or communicating ideas. Then examine actual degree routes rather than relying on the group label.
Check prerequisites in your curriculum
Read course entry requirements for your specific qualification. A subject combination accepted under one curriculum may not map directly to another. Ask the school counsellor or university how required subjects, levels and grades apply to your record.
Compare interest, preparation and workload
Use recent work and teacher feedback to judge preparation. Consider whether the combination leaves enough time for sustained learning. Choosing a subject only because it sounds impressive can close rather than open options if the workload becomes unmanageable.
Make an evidence sheet
For each route, write required subjects, your current preparation, evidence of interest and one unanswered question. Add the source and date. Revisit the sheet when course requirements or your understanding change.
