My last PERT test went amazing, I scored 124 after many attempts before using your program. The most helpful elements of your course where the diagnostic tests and the video reviews.

In school I had big problems with math and always considered myself like a liberal arts person. But with this course I prepared for the Accuplacer to be able to take classes I need in college without mandatory remedial classes and I even fell in love with math. And now I understand it very well, thanks to you, and I find it charming to solve different type of equations. Even though English is not my first language I was able to understand everything. So after preparation from scratch I passed this test very easily to the level I needed. So thank you, guys! You’ve made a great product!

I have to say how much I enjoyed your TX PACT class. It was a great reminder of things I haven’t done in years. Your explanations were so simply put and easy to understand. I felt confident while taking my test, and actually enjoyed studying for it.

My FTCE Math test went great and I passed. Your program was exceptional. I loved all facets of it. I like the fact that if you knew one component you could take an exit ticket and move on to the next section. The videos were awesome too.

It was all a great refresher! The higher level math (above basic addition and subtraction) was super helpful to refresh my brain on how to do many concepts I had forgotten about. I was able to pass the PRAXIS!!! I just referred a colleague to your site who needs to pass the test too!

The first time time I took the PERT I got a 103, and the bare minimum requirement was 114. The second round I used MathHelp to study, and scored 130 out of 150! The instruction videos, and practice tests helped me a lot. Everything about MathHelp is absolutely wonderful!

As a math-phobe, I needed as much help on the FTCE math test as could get. A teacher at my school suggested your program. I loved your back-to-basics approach to help someone like me, a 58-year-old who never liked or could do math. I found your instructions and lots of practice questions and tests to be extremely helpful. I took many of the questions over and over again to get the steps correct. I always especially had trouble with measurements and geometry, and I think your program helped ease my anxiety and confront those questions head on. It also helped me get straight in my head the positives/negatives and when they apply in addition, multiplication, etc., as well as how to take a word problem and make it into a solvable algebra equation. It was an extremely helpful program for me. Keep up the great work!

That course was the absolute reason in my success of the TSIA2 test. I did pass it and can take College level algebra instead of developmental math. Specifically speaking, the quadratic equations, functions/graphing, linear equations in two variables and expressions, equations and formulas really helped. So I'd most definitely give that course a lot of credit to helping me pass.

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 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!
