Reviews of Our College Pre-Algebra Help

"I was desperately seeking Algebra help. I am working on an Associates Degree at a local community college. Pre-Algebra and Elementary Algebra were required classes for me. I was completely lost because I have absolutely no Algebra background. I was really struggling in my class. Then I found The lessons were a tremendous help. I ended up making an A in the class and passed the exit test. Thank you for your help."

"I was not taught math beyond multiplication and division. (It's a long story.) My heart's desire was to graduate from college. So, I began taking college level classes and pre-algebra. However, I knew I wouldn't pass college algebra. I had a 4.0 avg. but without being able to pass the math requirements I would NEVER graduate. One evening, I was browsing online and came across ''. I began at the beginning, with college pre-algebra tutoring. I've learned SO MUCH and gained such confidence, I called the college today and plan to re-enroll. Next stop: Graduation Day! THANK YOU,! Well done!"

"THANK YOU GUYS SOOOOO MUCH! I'm using these courses from pre-algebra all the way through college. You guys rock."

"I needed this to work up the courage to apply for college as an adult...I shied away from the idea, because my math skills were horrible. But this helps greatly."

"The only thing standing btw me and my BS degree is ...MATH! Sadly, I have zero background in math beyond addition/subtraction/multiplication. YIKES! So pleased to have finally found a way to LEARN, really LEARN math! Work at your own pace, be able to go back and review and best of all ... CLEAR, CONCISE PRESENTATION! Thank you,, for this BEST EVER learning tool!"

"This is a wonderful site to learn and excel in math. Thanks to this site I passed my college pre-algebra exam with a 20 percent increase in my overall grade for the class. Thanks a lot."

"Before joining your website I failed placing into a college math class. After joining two months ago I took my College placement test and I scored into a Business Math class. I'm so excited. Your website is awesome."

"It's helping me prepare for my college classes for next year. Math is my weakest subject but this site explains everything perfectly! It has practice, self-tests, printable work sheets, instructional videos and even notes. I love this site and use it for college pre-algebra tutoring every morning before I continue studying my other subjects."

"I just love and the way you explain things. I felt like I was in a Pre-Algebra classroom instead of just looking at examples."

"I love all the "stuff" your website offers. Your teaching approach is wonderfully balanced utilizing the 'I do, we do, you do' method of teaching math."

"I use the program for College Pre-Algebra tutoring. I have always been horrible at math and through my life been very frustrated with my math teachers. is the best math instruction I have ever had. I appreciate the videos, they definitely work for the rest of us non-math types."
