This is a great introductory course for anyone who has been out of touch with math and algebra and would like some short reminders. My math knowledge is like swiss cheese and I decided that I will get back into it as a hobby.

If you are trying to restart that frozen brain of yours start with this course.

The course is a great way to review all the things I needed to take the GRE. I'm suspicious that some of the practice section problems might not accept the correct answers, though
