Use bootcamp, install windows. I have my mac partitioned for a class that doesn't work on a mac. I have a 250 gb hard drive on my mac, and 32 gigs of that dedicated to windows. You can just switch back and forth, super easy.
It's already on your mac. Just click the magnifying glass top right and type in boot camp. Start the program and print out the instructions. You'll need either a Windows XP or Windows Vista program to install on your computer, so get that. Follow the instructions you printed and you're good to go. It's super easy, I'm computer retarded and I was able to figure it out. There are also mad tutorials online about how to do it, just look it up on google.
yo everything free if you know how to use torrents, assuming you didn't know what bootcamp is, how to get windows for free, or anything else that's common sense, you deserve to but a new laptop for math homework.
