Maybe think about where you want to end up and what you need to do to get there
What do you want to do after A-levels? Most people I know go straight on to University. Do you have a course in mind you want to do?
It might be a good idea to look at alternatives to A-levels. e.g. Jobs, Apprenticeships. Cyber-Security is a growing sector and there are apprenticeships in Cyber-Security (I'm not sure of the requirements though).
It might be a good idea for you to have a look through university courses or jobs or apprentiships you might be interested in and find what requirements they have.
If you take any subject at A-level I reccommend maths.
A Maths A-level can be useful because:
- Maths is hard, you might not get the chance to have this much help learning it ever again.
- It is a requirement for quiet a few science based university courses.
- It is used a lot in some areas of computer programming/cyber security.
- Even some jobs after university will ask about your maths A-level if your degree is not very technical.
You will probably need to work really hard at it but I think it is worth it. khan academy is a really good resource that explains maths concepts well, better than most teachers.
Computer programmig can also be hard to learn so it might be worth dooing it for A-level. You will probably get the chance to do this at university though (depending on your course) so maybe there is no rush.
