I did 2 years at college. 1 day at college, 2 days for a pair of cowboys. Even after finishing the course my skimming and rendering wearn't realy at a high level. I would say after 4 years that I'm quit good, and worth the money I charge. I reckon though, it should take another 2 years before I'd class myself as very good. Level 1 is very basic, you could probably learn the same amount from a book. Best bet is to try and do some work experiance with your mate before spending any money. If you do the course then work with him for a few years. Good luck though
