Hi Pamela -
There will be slight differences in the requirements depending on which school you choose to go to, but for the most part, you can definitely expect to take some upper level math courses. The courses you take will also be different depending on if you decide to pursue a B.A. or a B.S. The B.S. typically as slightly more requirements. I was a Zoology major (pre-medicine) and was required to take Calculus and Statistics. If you don't have a lot of experience in math, you can also take pre-calculus and it will still count toward elective credits you need for graduation. I was also required to take a year of physics which includes a great deal of math and calculations! As a biology major, you'll find that almost all of your science courses have elements of math in them, especially in the lab portions. But don't worry, if you feel you aren't as prepared as you'd hoped, you can always join study groups and speak with your advisor when registering for classes to get some guidance on courses that may help you out.
