University of Texas Chemistry Pre-Req xpost

ARGH. I'm so freakin' confused. Is anyone here attending or planning to attend the U of T Nursing school? The handbook says that you only have to take a 4 hour lab Chemistry pre-req, but the way the course numbers are described you actually have to take 8 hours and if you didn't take high school chemistry you have to take 8 more. So it says only four, but it's actually 16 if you didn't have high school chem and 8 if you did. I plan to call them this week to try to get it straightened out because I'm freaking out about having to squeeze in 16 hours of chem along with my other classes, but does anyone know the answer?
