Can one math class make a difference in your academic standing? Curtis sure thinks so, and he has the story to prove it! “I worked with a student who took an online math class over the summer,” he explains to RD.com. “The student could have paid for a certificate, but I told him to save his money. As an added bonus, the student was able to skip ahead a whole year in his high school math curriculum. These achievements count a great deal in the college application process.” Not bad for a single free class!
