I'm thinking of going back to college to take Psychology. I did it about 4 years ago but failed the first year. The course lasts two years, first year is AS Level, second year is A2 Level. AS + A2 = Full A Level. The only thing I have to pay is the entry fee which is about £15. Also for this course I would have to take 2 or 3 other subjects along side it. And I don't want to take anything else, I just want to do Psychology by itself. But...
There is also a course (AL) which is a full A Level in one year. So it's both years crammed into one. This costs about £300.
There is no guarantee I will pass obviously.
I guess my question is, would it better to waste two years + subjects I don't want, OR, one year and £300.
I don't want to do the 2 year course because I don't want to take other subjects along side it. But then the full year course is a lot of money.

I hope I made sense Some advice please?
