I need advice on what course :)

Ok well i just came out of college from the courses i was doing cause i aint carrying on with them next year or stayin at the same college so yeah..

BUT
now i have applied for 2 courses at 2 different colleges
First one is an Art course thats for 2 years... and looks like i have been accepted. I always wanted to do be an art teacher an everythin so yer happy bout tht. But i got like a B in my GCSe and am waiting for my As level art result.. so i dnt no if i am good enough to do the course.
The second course is a hair and beauty course :)
Its like oooer.. i have like a taster day on monday and well the college is like FARRR but it means doing something ithink i would like doing.. but i dnt know whether its as good as doing art.

I just dont know whether to take the simple choice of hairdressing and being done in 2 years and ready to do the job straight away.. or.. do the art course for 2 years then going to university for 3 years to get the teaching degree.
Err.. i dnt no wot type of advice i am looking for.. but if anyone has actually done any of these courses it would be like Wooot.. and tell me what they are like etc..
Or you could just tell me what you think i should do.
[please dont make comments like do wot u thinks rite.. cus i dnt no]

Thanks for any help.
Will +rep to good advice/help
