when I first started doing A Levels, I was doing MAths, Physics, Chemistry and Computing. After two weeks, I knew that I wouldn't be able to change maths so I changed it to A level product design. The key here is that I did GCSE graphics, which I essentially just got to dick around on photoshop and sketch and stuff, and did fairly well in, whereas the subject I switched to was about woodwork. I wasn't told this beforehand, and told I'd be fine on the course with graphics background. (Note, this was the only subject I had the necessary requirements to do, the other being biology, but I couldn't take doing 3 sciences)

Anyway, so I realised on the first lesson that it was about woodwrok, but I decided to persevere because I couldn't really change subjects twice within a week, and because I decided if the teachers said I'd be fine, I'd at least try. Fast forward to now, where the work now involves things I've never heard of before. Seriously, I haven't held a saw for over 4 years, and we're expected to do metalwork and shit. Right now, I have no fucking idea what I'm supposed to be doing and as such, it's stressing me out and I'm not enjoying the lessons. And my general attitude is that I do worse in something if I don't enjoy it, and right now, I actively dislike the lessons.

To put on top of that, we have mock exams coming up next week, and I know that I'm going to fail it because I dn't understand anything. I don't want to get kicked off a course, but I don't see any other option. help?
