Where to start:Math

Hello,

I am an adult learner with an advanced degree in music. I am planning on going back to school for a bachelors in IT/CS in the fall. The last time I touched anything to do with math was around 20 years ago, and it was outside the US, so not in English. The degree program I will pursue requires several math classes as part of the curriculum, and so I would like to get a head start so I can hit the ground running. The problem is, browsing the list of math courses here, there are so many, and I don't know where to start... Could someone please help by recommending a few classes to start my math journey in?

Thanks!
