Well in that case good to hear your going to finish grade 12. My roomate is a ticketed Carpenter, he finished last year all i can say is for the 6 weeks he was in school i barely saw him because he was so busy studying and doing homework. The stuff he showed me that he was learning was pretty intense, lots and lots of math, tons of stuff to remember from the huge code book. Concrete stuff, load bearing, sheer strengths of nails and screws and other fasteners. It looked like a lot to me, but then again i'm a Mechanic not a Carpenter.
I never once heard him complain and say it was a shitty course, just that when your in school for the 6 weeks they throw a lot at you, but my apprenticeship was the same way.
