"Being 39 and going back to school is tough. It has been 17 years since I did any real math problems so starting out with Algebra was more than I could handle. Until I was referred to Videomathteacher.com This site has everything, a video library, work sheets, and an abundance of material to choose and use. Now because I have been using the site my Algebra is improving and I may get a respectable grade in my class now. Thanks Videomathteacher."
