I need some advice?

I'm starting 2 a levels so I can joing the RAF should I pass at the age of 21. I've put money into doing this and quite a bit at that, as I'm outside of the free education age, but I feel like I fear failing (I haven't since my GCSE's). I'm studying law and history, but I need some tips, it's an online adult learning course.

I've never really strived to be an academic sort of individual as I'm more of a manual worker. How can I do this without blowing up from stress or fear of failure?
