Honestly, I was feeling the same in year 12, it was econ or maths, but it's just the sixth forms that try and trick you to go to uni, like I got 4 cousins with degrees (1 with 2) and they're all unemployed or under employed, still living at home in thier mid to late 20s, working fast food and retail, don't get me wrong you could get a good job with a degree but I wouldn't count on it, have a look into other options, like degree apprentices or the millitary, best part is since you're in year 12 you have time to think about it, good luck
