I noticed that many schools don't require it, but I am taking it because one of the schools that is one of my top choices (Stony Brook) does have it as a prerequisite. It seems like a waste of money to me, but I feel like I would be blowing my chances of applying if I didn't take it...and trust me, I'm dreading it because I hateddddd chemistry in high school (which was the last time I took it! lol). I believe another school or two that I am applying to may look favorably on the fact that I've taken it, but they don't require it. So basically I'm spending 600 bucks to apply to one school. Yup. Fun.
