If you have all your pre-reqs done and they're credible, I think WCU still makes you take their chemistry. They're not taking the basic chem that's offered in community colleges. They say its because its not the same as what wcu teaches (even if it does have a lab). Regardless, plan on taking Chem, and with that you're looking at a tuition to be about 35k-38k...from what i'm hearing right now.
Hope this helps.
