I don't want to discourage you, but it is not going to be like, Calc 2, and then no more math. Calc 2 is the least of your worries as a compute science major. I am not a cs major, but from those I have talked to, it is not what they were expecting. It was very mathematically oriented and very theoretical. It will be very hard without good math skills, but still possible. Go with your gut, but be reasonable. It will require a lot of math!
