If I remember, it's basic trig, calculus, and algebra. They sign you up for both trig and Calc 1, and if you do well on the entrance test, you can drop out of trig. However, since there was no extra cost for the trig credits (it was like 18-21 credit hours was the same price), I stayed in the class for an easy A and a GPA booster (it paid off senior year).
I had AP Calc in my high school (but only got a C in it), and so the math placement test wasn't too bad. If you have never had calculus before, you should still be okay.
However, if you can't handle the math early on, just remember, it's all uphill from there. After differential equations, Laplace and Fourier transforms, and complex integrals and matrices, I started longing for the "good old days" of Calc 1. And as an AE, you are going to have to know LOTS of trig functions. My AE friends (I was EE) had to enter various arc-tangent functions into the AutoCAD software to get their wing curvature just right in their Drafting 101 class, so they used the trig early and often.
Good luck!
