Yeah...as everybody else is saying, I'd go with it. I took IB (2 years ago now
) and I'm at UofC (Taking Business) and I can't really say I've got anything out of taking IB (Then again, I haven't had to take any sciences or anything...)
Hopefully it'll be an easy A (Kinda doubt it though) and there will be some new material...
And as everybody else is saying..I've heard that Elsabrouty is the best math prof out there, so try to get in his class, stay away from any class with Dr. Mollin...
