The stuff that isnt calc is just mostly algebraic manipulations. But as others have said calculus ranges from some to a lot of the test. I took it in June of 2005 and cant remember doing anything but guessing on the calc questions (it had been about 6 years and I ran out of time to reteach myself) and still got an 85% on the math. Not really great, but if you are able to get high enough scores on the other sections you can theoretically score just fine overall on the exam.
If you've taken all your bios up through physiology, chemistry up through organic and are extremely skilled in the english language areas you can take it. If not, I'd wait, at least until the fall when you'll be about 1/2 way through calc.
