when I looked at a practice exam just now. Holy shiat! It wouldn't be bad at all if I had actually studied for a week or two, but there is no way I can go into that test cold. Looks like its IC for me.
yea, it's best to have some prep. the biggest problem is running out of time. problems usually have some trick or formula, else you gotta do it the long way if you don't remember how. when i took it, you could miss 8 and still get 800. i only walked away with 790
Math IIC was easier for me than IC. Must be because now that I am in calc, we do more trig than basic algebra. I got like a 760 or something on IIC, and a 690 on IC. I did take the IC at the end of last year, but I don't think that made that much of a difference (last test of school year vs first test of school year).
