If you have an 'art gene' in you it will always find it's way out! I would get 98% in art and, in the same exams, 7% for science and don't talk to me about maths! There was no doubt which way my life would go!
I did a Foundation year at Art College in the Uk and a Fine Art degree in SA but was constantly frustrated by the professors attempts to change me into what they considered an 'Artist' to be.(My work was very representational, as it is now, and this didn't suit their image of art)
I have found, since coming back to painting after many years away form it, that the best way to learn is to study other artists and even copy work you admire. You learn a huge amount by actually emulating another pieces of work and learn technique this way quickly. I also devour art books, go to galleries and trawl websites.
One thing that
was very good advice from a lecturer at Uni was; "You must look at images all day, look at books and fill your brain with resources to draw on". This has been one thing that has always stuck with me and I am sure he was right.
Having gone to Uni or college to 'learn' Art, does give you the bonus of being more appealing to some galleries but, does not necessarily make you a better artist.
A great book and course that I have always meant to look at and do is; "
Drawing on the Right Side of the Brain' by Betty Edwards (ISBN 0-00-711645-4) Maybe give it a go?
