Everything depends on your area of expertise. You have to understand Stats to realize how they can be manipulated to say whatever you want them to say and thus how bogus they are. Statistical analysis is only relevant in the insurance industry, IMHO.
Be that as it may, If you can get a hold of the text that your course will come from you will get an idea as to what you need to relearn. Then get a good PreCalc text book from the library and go over it. Then get a Calc I book and read thru it. Use the tutor sites when you can't get it yourself. Mostly, education is teaching others how to teach themselves. More than likely, because your brain has matured a lot since college, you will "Get" math in a way you didn't before and love it.
Have fun!
