Which is the right University Course?
Totally agree with 4kBeta.
Only consider courses which you are genuinely interested in. This will be the area where you will be most likely to excel (and also not drop out of - which is always a risk).
The idea of a University education is not to cram your head with 'facts' but to teach you how to think. This will be of great value to you in later life - but possibly not financially.
It is always wise to have a back up plan. In aviation the risk of losing your medical is always there. You have to minimise the potential risk.
What A levels did you enjoy ? What does that tell you about what areas of life you want to learn more about?
Good Luck
