It’s been difficult learning the math that I missed or forgot from 35 years ago, but I did it. Your amazing, well-thought-out instruction helped me to understand math concepts. More importantly, you taught me to think critically about problems and to take my time solving them. This has influenced other areas of life! The results are that I passed the math portion of a crucial OGET test! This is now opening a door for me to work and make a living for my family, and in my later years, for me. How can I say thank you?! It’s been a joy learning with each one of you. I may even keep going as there was still so much to learn and you made it fun. I now understand that math is just a language. Your program breaks it down teaching step-by-step in very doable ways. Thank you so much!

I was more than satisfied with the math help program. I only got 2 questions incorrect on the math portion of the TABE test. I don’t remember having any issues going through the lessons, and always felt more than ready moving to the practice portion, then the test portion of each lesson. Each video was at a very easy pace to follow it was clear and to the point. I loved having the practice portion and always felt there was enough to practice on to really nail it down. For me my main issue in school was when the teacher would ask “ok does everyone understand it? Ok awesome moving on now” I was always not ready to move on because there was never enough repetition for me to really truly understand the material I was working on. There was material that I struggled with really bad in high school that I immediately was able to grasp during your lessons. If I ever encounter a period in my life and schooling again where I need help on math I will surely come back to math help. Beyond the teachings; the UI of the website and how smoothly everything worked was definitely a surprise for me. Thank you for the help.

The lessons helped me tremendously on my math placement test. I’m attending the University of Alabama this fall. I finished my associates degree in 2016, so I haven’t taken math classes in a long time. After doing the lessons I placed out of the intermediate classes I didn’t want to take, and into calculus. Taking this course has saved me around $2,000 in classes, and my graduation date was moved up. I’d say it was a great investment!

Your lessons were phenomenal, and I would be remiss if I didn't give proper feedback.Let me just start by saying I have been putting off (and dreading) taking the ALEKS Math Assessment for about 2 years now. Math hasn't always been my favorite subject, but as I'm getting closer to completing my degree, I could no longer avoid it. I knew that there was a possibility that I would have to take additional courses before I was permitted to take the courses I need for my degree, and that would have pushed my graduation time back, depending on how I performed in those classes, first. With that being said, I found the Mathhelp site, saw that there were great reviews, and decided to give it a try.Going through the lessons, some concepts that I didn't understand in high school, somehow made plenty of sense this time around. I found that your lessons specifically, were the ones I was able to most understand. I think it's your teaching style. You explained things in a "relaxed and casual" way, which made the lessons seem more personable and one on one. The other 2 instructors were great too. 🙂 I had a high hope that these lessons, by some miracle, could possibly help me to test out of any prerequisite classes I would need. Although ALEKS gives you 3 attempts to take the test, I didn't want to have to retake it if I didn't have to.Anyway, I finally took the plunge (ALEKS Assessment attempt #1) and tested out of the prerequisite courses!!!!!!!!!!!!! I'm not exaggerating when I tell you I was close to crying when I saw my results.The lessons were everything I could hope for and more. Thank you so much!

MathHelp helped me so much, I like how the teachers/professionals explain things step by step, I took my ASVAB and scored a 91, I have never been so confident with my math knowledge in my life, mind you the first time I took the test I scored a whopping 15.

I took the ALEKS test prep and it went really well because of the help from this program. I got into the class I needed to place into. I think the most helpful thing that was provided was while taking the tests at the end of every question I could see how the math was supposed to look if I got it wrong. It was really helpful for me to go back through that math that I blocked out in high school.

My daughter used Mathhelp.com to prepare for the Accuplacer math placement test at her university. The school required a score of 279 on the Quantitative Reasoning test to move on to the Accuplacer AAF. The first time, she took it cold and scored a 270, so she was not able to move on to the AAF test. Then she studied on your site and got a 299 on the QR and a 292 on the AAF test, so she is good to go!Your website is very well planned to maximize results while minimizing time investment. The method that worked best for my daughter was to take the practice quiz for each section and then read explanations or watch videos of the problems she missed. That way she wasn't spending time watching videos on topics she already knew/remembered well. I then had her take the full practice tests once she had gone through all of the videos she needed to. Sometimes she didn't even need to view the videos -- your explanations of answers were sufficient in most cases to tell her what she needed to know, but the videos were very helpful when she needed a bit more explanation/step-by-step instruction. Up until this year, she has always done well in math, but a crummy teacher combined with covid virtual school made this year a very tough year for her, and she has lost a lot of confidence as a result. I hope that seeing how well she can do with a bit of good teaching/support has shown her that she can be successful again in this college calculus course.Overall, I was very impressed with how well your website prepared her for the tests, as evidenced by her scores. I will also use your site as she prepares to take the PSAT next year.

I first want to thank you for the MathHelp lessons. They are well done, in a logical order, and I appreciate that they are short, explain the concept with an example (or more), and that there are practice problems in addition to quizzes and tests -- all with the work written out and explained so I could figure out where and why I went wrong in a problem -- and affirm what I did right. It was the best review of math concepts I found while looking for assistance to prep for the ALEKS math placement test at the local community college in which I enrolled. I am 25 years out of grad school (in a social science field), and as I am jumping back into school to pursue nursing -- a heavier math and science field -- I needed to review the concepts that I was able to test out of a few decades ago.I also liked that I could watch the video at double time speed if it was something I just wanted to quickly review :) The examples with word/story problems also helped immensely! I was faced with a couple of them when I took the ALEKS test, and since I had practiced them (their format), they came a lot easier to me. And finally, the fact that there are links to related topics within each lesson made a difference. I checked out a few of the links to related lessons along the way just to make sure I was understanding things as fully as I felt I was, and those lessons reinforced what I knew and gave me confidence to progress to the next section.As for ALEKS, I scored more than what I needed to place into the math class required to complete my prerequisite for the nursing program. I would highly recommend MathHelp!

This program was so helpful. I haven't taken a math course in 20 years and needed to refresh before taking the Accuplacer and going back to school. The test went great, I got a 292/300. It was so great to have access to mathhelp to refresh my long dormant math skills. I found the lessons clear and easy to understand. I loved the feature of being able to skip lessons I already knew. The little diagnostic quizzes were great to let me know which lessons I needed to take and which I could skip. Thank you for your work, I found the website to be such a helpful tool! I would recommend to anyone!

My CASA test was a breeze, thanks to the practice from the MathHelp course. I believe the most helpful sections of the course for me were the explanations for the more involved word problems. I also needed refreshing for graphing inequalities and volume equations. I benefitted most from the clear explanations and thorough solutions presented in the course. Class video length is spot on and the five question limit for each test is enough to challenge, but not intimidating or discouraging. Thanks for your great test prep.

The ALEKS lessons were indeed very helpful. Your explanations were clear and well laid-out. I’ve been away from math for nearly 30 years now, and I frankly struggled back then when I was learning. Today, I scored an 84 on my ALEKS placement test, which qualifies me for honors math placement within my school. I’d say you guys are doing something right!If I were highlighting a part that was particularly helpful, I’d pick the logarithms. That’s an area that always flummoxed me, but your explanation has turned that weakness into a strength. Simply brilliant.

The course helped me SO much!! I went from not knowing ANYTHING to making a perfect score on my GACE math program admission test! I literally felt doomed before I took this course. I think each of the teachers did a great job breaking everything down and simplifying it. I honestly don’t see how it could be any better. I really feel like I FINALLY understand math now after years and years of hating math and not understanding any of it. Thanks so much for creating this course and helping me get one step closer to fulfilling my teaching dreams!

I absolutely loved my experience with MathHelp. I am going back to school to get my Masters in Architecture and haven’t taken a math class in 20 years, so I needed to bone up for my Structural class. I appreciated the cumulative curriculum and the online quizzes/ tests with immediate feedback showing work when I got a problem wrong. Also, the ability to download the test scores printout / excel is key. Thanks again for a great service!

I took my PERT test this afternoon and got a 139! Was able to skip a bunch of pre req classes, so thank you. :) I hadn’t taken a math class since high school 7 years ago so the review definitely helped. The videos were very easy to follow and the practice questions and mini reviews at the end of each section helped a lot. If I ever need more help I’ll definitely be using Math Help again!

I’d like you to know that I absolutely love the Intermediate Algebra program, and will likely be signing back up in January for the College Algebra course. I’m 36 years old and have always struggled with math, barely graduating high school because of it and so I began with your program for the PERT test, which allowed me to get a high enough score to pass taking a remedial course.Continuing with the Intermediate Algebra program during the semester is absolutely the reason why I was able to sustain a B grade, and I actually have my final this afternoon and I am confident I will do well.I think the reason that your program works so well is because you keep it short and to the point. All the steps are shown, you don’t use a bunch of extra words and jargon, and you keep the problems simple so the student gets a chance to perfect those before going on to more difficult ones within their actual class assignments. There were several places where the things you taught weren’t explained in class notes by my school that made a world of difference (such as clearing the radical in the denominator, or using a factor tree to factor rather just trying to guess multiples). It also helped that your course guide exactly followed the flow of the class going from chapter to chapter so I could watch my class lecture (online course), attempt some of those problems...I’d struggle, then I’d go to Mathhelp, do well, and go back to the class coursework. It was an easy lateral movement. My not getting an A in the class is simply because I make silly mistakes like forgetting signs or the simplest math errors, but I feel confident in the course and that’s simply 100% from your program.Thank you for all the help your program has offered, it’s been quite an amazing transformation for me.

It had been years since I had done basic math like that. It was nice just to have a refresher on all of the CBEST concepts. Most of the practice tests I took were very spot on. I would say you guys covered most of the basics someone needs to know! They do a scaled score from 20-80 on the test and a 41 is passing. I actually got a 70 on the math section so I did pretty well! Thank you again!

I graduated high school in 1992, that was the last time I did any math related to algebra. I never went into college. 20 plus years later I decided to enroll. I needed to take the PERT placement test for Math. I had a bit of panic because I didn't remember anything; so I would have to learn as much as I could within a month because of deadlines with the school. I stumbled upon MathHelp.com while google searching Pert Test help. They offer 3 free lessons and it is a nice introduction into how the website works. I signed up for a month.Topics are broken down into a specific area; ie: Quadratic Equations. These are further broken down into bite size lessons that go through a specific part of the main lesson. Each lesson is explained in a logical and practical way that is easy to understand. After each mini lesson you can either practice or take a test on what you learned. When you finish a topic you get a review test on mixed questions based on all the lessons in that topic.I studied with them 2 hours a day minus weekends. Though I didn't get through all the areas because of time restraints; I did manage to go through the majority of it.The day of the test arrived and a few questions that I did not recognize were on the exam. However, even though I had not studied those specific problems, I knew the process on how to work through them. In the end for an old dude who hadn't studied in a long time I scored a 124 out of 150, enough to be able to select college Algebra. If I had been afforded the time to hit every section and really get mastery of it, I probably could have scored higher.I highly recommend signing up for this site if you are struggling with higher level math and or need a refresher on it. The teachers are amazing and each lesson is presented clearly and simply. The fact that you can practice them over and over really reinforces their lessons.Another good thing is unsubscribing. Most sites are sneaky and in order to cancel you have to find a number from some other site. While MathHelp.com is auto renew you can basically just click a button that says unsubscribe.If I end up having trouble in math this semester I will definitely be subscribing again. I can't thank them enough and highly recommend them. Worth every penny.

This course saved my life as I was trying to study the math content for the GRE exam. The last time I studied math was over 7 years ago, so my math skills were almost non-existent until I found MathHelp.com. The course for the GRE was incredible - it covered all the material for the exam. The instructors are experts and very skilled at teaching the math concepts in a very clear and detailed yet broken down manner. I also like the practice questions which prepare you for the test of each lesson. The bonus material added to some lessons is also extremely valuable especially for the nature of the GRE questions. I didn't notice any shortcomings from the program honestly. Looking forward to acing the math section of the GRE. Thank you for the creators of the website and the instructors' hard work in delivering this top notch content. I give this course a 5/5 rating.

Pros:- explains math lessons slowly and thoroughly.- Has worksheets, answer key, tests printable for most of the material- Teaches college algebra, but it's exactly the same as Algebra 2 in the High School section.Cons:- Does not have worksheets, answer keys, tests for most difficult material- Stops having teacher standing in front of board half way throughAlgebra 2 and simply has a dubbed speaker.- Does not explain Bonus questions anymore half way through Algebra 2- Costs $50 a month, which feels a little steep for petering out on Alg 2- Does not really teach past Algebra 2 or Geometry so work incalculus or trig is not covered with this site. High school students inhigher math classes will not find help here.- The word problems are incredibly sexist. Cooking, sewing and cleaningword problems use girls names and building, computing, business,use boys names.- Have found quite a few mistakes in the answers, the problems and in the lessons themselves. I let them know, but apparently, they don't correct mistakes.In short, I do not usually recommend this site to my math students and their parents.

I passed my tests! I was using this service to refresh my math skills and it worked. I appreciate the service! You all do a great job. As an adult, I realize that we don’t always maintain knowledge if we don’t use it. Your format reintroduced me to proper methods, gave me time to practice, and then tested me. It was worth every penny for the positive learning experience.
