Pre-Algebra Reviews

"Prior to using your program for Pre-Algebra help, my daughter had 6 test grades of 45-56. Once she was on the program, she had 4 test grades of 85-100. She actually sits down with the Pre-Algebra program on her own and completes the work without me nagging her to do it. She does not have to be driven to another location, she is not losing school time to attend tutoring, nor am I losing time from work. I'm not praying that the tutor knows what he/she is doing. And you cannot beat the excellent price! This program works and is such a blessing."

"I am in 7th grade, and I needed some extra help with Pre-Algebra. The videos are perfectly paced and simple but helpful. I used to hate math, but now with this amazing program, I could stay up all night. DOING MATH. I sound crazy. But the challenges are fun to do and I'm very grateful to the creator of the website. THANK YOU. Anyway, get this program for Pre-Algebra. If you don't, you're crazy, because this is just what you need."

"My daughter is in the seventh grade. We are using the website for PreAlgebra tutoring in conjunction with the Glencoe PreAlgebra book. What a great help! I recommend this website whenever I can."
Eleni

"I'm a principal of a middle school and I am very impressed with MathHelp.com. Instruction is precise, concise and no b.s. You guys really have a great tool. Pre-Algebra is simple when it's taught by someone who really understands it."
Chuck

"I am using MathHelp.com to assist my granddaughter who is 13 years old and in the 7th grade to improve her Pre-Algebra grade in school. MathHelp.com has most definitely taken the frustration of me not knowing how to work something out when I am working out math problems with my granddaughter. Your Pre-Algebra tutoring has made showing her how to do something so much more enjoyable for the both of us. Please continue MathHelp.com."
Karen

"My son uses the program for 7th grade 'honors' Pre-Algebra help. I must say that the program is terrific so far. It clarifies and reinforces what my son is learning. I should mention that HE is the one who wanted to subscribe!"
Chantal

"I found out about you from the Pre-Algebra teacher at my children's school. They are both using Glencoe text books and it is a great supplement to those text books."
Amy

"I am the parent of two students, one in Pre-Algebra (7th grade) and the other in Algebra II (9th grade). Both girls have enjoyed using your site, and found it particularly helpful when they were preparing for final exams in January."
Susan

"I'm starting in 8th grade and I had problems with Pre-Algebra till you guys helped me. Love this website!"
Edris

"We have found your web site indispensable. The explanations and examples you give make learning Pre-Algebra so much easier - especially for visual learners. Even I have said a couple of times, "Oh! So that's how you do that!" We also like it that you have notes that can be printed out for study reference, and have extra problems for practice. I have recommended your site to so many people. I don't know what we would do if you ever closed down MathHelp.com. It saves me time not having to do relentless searches for 30 minutes or more on the internet to help my kids with their Pre-Algebra. If they don't know how to do a problem, I tell them to go to MathHelp.com."
Valerie

"Love the program. My daughter had a Pre-Algebra tutor for $75.00/hr. Needless to say, your program is far more economical and she has benefited. I also use it for myself to refresh my memory so that I can help them with homework. I plan to renew my subscription. I have also highly recommended the website to friends."
Donna

"What a HUGE help your Pre-Algebra tutoring has been! My daughter and I can view a lesson together...she hears it presented from a "different" teacher and I receive a refresher lesson so I can confidently answer her questions!"
Ellie

"This fall, my son is using the site almost exclusively each day to better comprehend his Pre-Algebra assignments - the index of lesson assignments to the textbook is a sensational feature. Thanks again for the wonderful service you provide."
Dennis

"The ability to study directly from his Pre-Algebra textbook and find the lesson on your website is huge! Great idea! I was also presently surprised that the product was represented honestly."
Lisa

"When I sampled one of your lessons, I knew this was a program that would benefit my son. The same day I purchased our membership, my son and I sat for two hours and completed an entire Pre-Algebra lesson with all the supplemental activities. After we finished, my son said that the instructor on the video was better than his teacher and he understood everything."
Elizabeth

"Excellent site for pre-algebra!! The lessons are easy to locate, and have been very helpful in teaching my middle school child pre-algebra. The videos are clear and concise, the example material is easy to understand, the tests are scored and the practice documents are extremely helpful. I would highly recommend this site for homeschoolers and have written a review on my blog for this site. Thank you to the developers!!!!"
Benjamin

"Thanks, this website really helped a lot! I used to be in regular Pre-Algebra but I moved up to advanced and the math there seemed pretty difficult. But thanks to you guys I think I can pass this upcoming test and stay in advanced Pre-Algebra. Thank you again!"
Ethan

"I'm going to be an 8th grader this year, and I forgot nearly EVERYTHING I learned in 7th grade Pre-Algebra. I thought I was doomed, then I found this site. It teaches you everything in Pre-Algebra from subtraction to properties to algebra. I definitely recommend this site, because it is great for reviewing previously learned skills. I wish I could thank you in person! I will definitely use this more during the school year!"
