DONT CALL IT PRECALC - it makes it sound harder than it is :@
I have a kid in my class who advertises his Math 11 as precalc 11 when hes just learning cosine law - I was like /fp.
Trig isn't too hard but algebra won't help you much; some memorization of some laws but all in all it isn't too difficult - you'll do fine. Graphing is based off of some memorization and less understanding(at least I found).
I'm taking calc next semester =F - I finished MA12 in summer school. In Canada we just have Math and it goes all the way to GR12 we don't divide it into algebra and geometry etc...
BTW: I'm jelly - I can't wait until I get accepted into BCIT's EE program - but it was just accredited 2011 so I'm scared >=(
