(I'm simplifying for the sake of explanation, but anyway...)
There are basically 2 types of careers (excluding athletic): academia and professional.
- Professional studies (and applied sciences) are more useful if you want to land a "proper" job (doctor, lawyer, engineer, teacher, accounting, architect, journalism ...).
- Academia (arts, fundamental sciences and humanities) doesn't lead directly to many jobs. Only research or teaching that subject (biology, classical studies, history, philosophy, English, political science, physics...).
Okay, that's a simplification, people with a degree in English can work for national newspapers etc, but the career path is not so obvious.
So in response to my comment that business is more useful than sciences, that's the reason why. Professional studies lead to proper jobs, academic studies do not.
Some interesting personal notes though:
1) arts degrees are great for growing as a person. But since money is limited for attending college you have to worry about your career first and foremost
2) I took maths, further maths, chemistry and physics at A-level and am now a computer programmer. But combined those A-levels barely helped me at all. I actually found Latin and English the most useful for being a programmer (and I was terrible in English).
3) University admissions committees require certain A-level subjects for their degree, but that doesn't mean you need the content of those subjects actually matters. And when it comes to getting a job, having ANY degree is 80% of the challenge overcome (it gives you credibility). The actual degree you take may matter a lot less because you learn 'on the job'. I emphasize that's personal experience - you don't want to be a surgeon and not know how a heart works :|
BTW, I seriously recommend you have a look at this page. I wish I knew about this at age 16: http://en.wikipedia.org/wiki/List_of...ic_disciplines
