After 4 years of finishing high school, I now have the opportunity to start college. I took the math placement tests and I scored low on math. The counselor suggested I take the summer to study and retake the math test and I could skip a couple math classes, saving time and money. I agree with that because I knew the material back in high school but I just got rusty. Any suggestions will be appreciated, thank you

Oh. My. God. You just described someone whose life will be changed when they use khanacademy.org.
The website is 100% free to use and has over 2100 videos on mathematics, science, and humanities. The math portion is by far the most comprehensive, covering everything from basic arithmetic to algebra to trigonometry to calculus and beyond!
The videos are arranged into youtube playlists, and you can sift through them easily at the site, and each video is about 515 minutes long (90% are 10 minutes or so).
The site is great for refreshing yourself (just what you need!) but if you're interested in learning something new, it's perfectly capable of providing that too!
There's a section of the website that allows you to practice learned concepts with randomly generated problems, and you can earn badges and points etc...
Remember! and it's free!

It'll change your life :P
