I passed the PRAXIS with the help of your program. I really liked the break out of each section and the grades it showed of my test while working through it. I really like the practice test questions with instant feedback if I got the answer correct or not. I like that I had the final exam as well and it helped give a snap shot of the areas I need to work on. I had used another program but did not pass my test...thank you for putting this together. I like the bonus buttons as well if I needed more work in a certain area. The blond teacher is the best and good to see other instructors as well.

I loved your teaching throughout this program! Thank you for all the hard work you put into compiling and teaching such a stream-lined curriculum. I only needed to test into MAT142 at Arizona State University to continue my education but it’s been 15 years since my last math course and as a nurse, I use some basic math for drug dosage calculations or area under the curve for chemotherapy calculations but this program was a great refresher for everything in between. I had super limited time to view the program, so I had to skip some on the more advanced trig, calculus and statistics sections and go ahead and take the ALEKS test so I could enroll for spring semester but I was able to test in to the math class I needed, so I consider it a success. I wouldn’t have felt anywhere near as confident going in if I hadn’t completed the program first.I definitely think every section was very well thought out. The practice questions and the test questions were a definite bonus. It gave me plenty of chances to try out problems without guidance and the ability to review the written out solution for each answer was phenomenal. I was also grateful for the ability to skip around, to see my progress and scores and to be able to speed up the audio for each section. The reminders and pointing out the common mistakes that students make was a great touch! It made me think about what could trip me up later on and those little tidbits will stick with me.I sincerely appreciate your help and I may be back later on if my course doesn’t provide the caliber of teaching that this program did.

The ALEKS test went as well as it could for somebody that’s been out of the classroom for 25 years. The MathHelp site actually helped me a ton to prep. I don't have to take remedial math thank goodness. The ALEKS prep broke out the subjects beautifully and allowed you to build on it if you needed to. I hopped around a bit myself, but overall super easy to navigate either way you do it. Thanks!

The Accuplacer went great, I was studying to place a class higher and was able to accomplish that goal. What I appreciated about Math Help was its clean layout and structure to be able to move quickly between videos and practice tests for each skill. I really feel like using this tool was a crucial part of me being able to advance in classes so quickly.

The course and the format were very well thought out and it did help me to pass a university math placement enough to not have to take remedial college math classes. It was good refresher even though being away from university and college math for over 30 years. I would highly recommend this math help for anyone that needs to get back to the basics. Also, the way it is taught with explanations, practice problems and test questions for every concept covered.

Thanks to Mathhelp I scored three levels above where I needed to be on my Aleks test. Fantastic course. I really liked how you could change the speed of playback - I would usually watch at 1.5x speed. If I could have done that when I was taking math in high school I wouldn't have been so bored. The tests and review units were all really well done and everything helped. Thanks so much for all the work you put into this, it's really great!

This course was amazing!! I recently went back to school and had to take the Accuplacer test for math. I have not been in a math class for over 14 years. This course helped me pass and get placed in college level algebra. Definitely recommend this course.

My daughter did well on her math placement test to get into college/honors calculus for her high school. She improved her score by 40%. The program helped her "learn" how to study.

The ALEKS test went great. I hadn't taken a math class for over 5 years so I was a little nervous to take the test so I wanted to be as prepared as possible when taking the test. It was really helpful in refreshing my memory and teaching me things I never learned. What I found most helpful was the video lessons as they helped walk me through everything. The program was really helpful.

Preparing for any test can be nerve-racking, especially when it’s a subject you struggle with or have not practiced in a while. When I needed to prepare for the Accuplacer Quantitative Reasoning and Statistics I found all the resources I needed on MathHelp. The lessons are concise, thorough, and easy to understand. When my test day rolled around I felt confident in my abilities. I ended up passing with flying colors and even exceeded my own expectations. I would recommend MathHelp to anyone who wants to improve their understanding and confidence before their test day!

passed the TExES core subjects ec-6 math exam!!! The videos really broke down each skills for me. I liked how many practice questions there were after each lesson for practice for the test for the bonus. I really liked it. The videos with the blonde woman were the most helpful. I feel like she really broke down each problem and explained each element that helped me a lot.

Thank you! I passed my NYSTCE Grades 1-6 exam and did surprisingly well. I haven’t taken a math course in 20 years so I was nervous. I liked that I could go through all of the lessons, test my current knowledge and then focus on the areas with the most need. I felt the lessons were taught at a level I could understand. I appreciate the course I took so much, it helped me out for sure. I got a 557 on a test that I thought would be near impossible for me to pass.

I annihilated the TSIA2 test! The most helpful part of the course for me was it’s step-by-step format and practice questions and its slowly ramps up in difficulty - which kept me motivated. The way the course is formatted made it incredibly satisfying and easy to learn.

The Accuplacer test went well and my daughter scored high enough to get into the college math class she needed to take. We really liked the program. It was great how there were the explanation videos which were really good and then the practice and then the quizzes. I liked how if she already knew something we could skip right to the quiz part and if she was struggling with something we could watch the explanations a couple times and then see the practice problems worked. I wasn’t sure how I was going to get her ready for that placement test before I found your program and it was just what we needed. I would definitely recommend it.

My AccuPlacer test went very smooth thanks to the MathHelp lessons. All throughout the course I was thinking “this is refreshing my brain so well, while also teaching me lessons much more efficiently than what I have learned in the past”. The course was great.

I haven't taken a formal math class for 25+ years. I was worried about the placement test for re enrolling in college. Math help did a great job dusting off the cobwebs and taught me enough to get into the course I needed. I thought the lessons were very good and thorough to give me the refreshers I needed to get the job done.

I am very pleased to say that I was able to pass the PRAXIS Elementary test on the first attempt. This wouldn’t been possible without mathhelp. Everything that was offered during the course I saw back at the test as well. For me everything was helpful especially the extra explanations and the subtests.

I'm 47 and recently needed to use your site in order to get a training grant for an IT certification. I did well on the CASA exam today - not a perfect score or anything but I passed comfortably. I like how each module is set up. Watch the video, work on practice problems or bonus if necessary and then do the test. I would have loved something like this in grammar or high school. Each module reminded me of the old math books without the extra unnecessary stuff just get right to the point. You guys have a great website, keep up the good work!

Mathhelp was so helpful to me in passing my ALEKS test and my two other math classes. I am now a college graduate! The instructors were both knowledgeable and patient and the lessons were easy to follow. I could test myself over and over till I understood a problem. As a “non-math person,” whose last math class was over 35 years ago, I would never have made it without Mathhelp. It was worth every penny and then some. I. Will always be grateful. Keep of the great work.

My ALEKS test went well when I used MathHelp! The most helpful tool to use was the review at every section and especially the final exam feature at the end. I loved having practice taking math tests again. It had been a long time! I loved how if I had a problem understanding any topic, I could use the links provided to go back and understand the background for each step. (For me, this applied to a lot of the exponential expressions and geometry stuff). I can't thank you enough for your program! It was great and I feel so much more confident about my success in my math classes coming up!

I passed my TSIA2 test, and honestly I tried out so many different websites; Mathhelp was by far the best and worth every penny! It was easy to follow and went over exactly what I needed to know.

I’m a huge fan!Both the Accuplacer and ALEKS courses were spot.I set a goal to see if I could cram learn and test into precalculus/ trigonometry inside of just two weeks - and I did it!I sincerely could barely do the foil method and I didn’t even know how to do long division and because of the course, and particularly Matt’s clarity in the lessons, I now play with functions for fun. :)Super grateful.

I PASSED the PRAXIS test on my first try after using your product. Not only did I pass, I got a 166!!!! That’s a score I never thought I’d get. The small snippet videos were definitely a game changer for me.

My math placement test was so great, I was able to enter directly into my college class without taking the test a second time. I am so grateful. The elements of the course that were most helpful for me were radicals, addition of polynomials, measurements (a lot of questions here), inequalities, and word problems. Again thank you so much, my twin brother is about to subscribe because he also has a math placement test very soon. I told him about this, but he did not believe me. Now, the results have spoken, and he wants to take the course too.

My PRAXIS test went well - I passed. I wouldn’t have been able to without this course. Thank you! I liked being able to “test out” of a section. I also enjoyed the explanations with each part. I believe it was comprehensive and well structured. Thank you!

Aleks test went well. The videos combined with the practice and test format with extra help videos on the side were great. The course is laid out perfectly.

Helped me complete a placement test to land in the class I need. The videos were super clear. They showed EVERY step, which had been a problem I was encountering with other learning sites. The instructions were well paced and easy to follow. Also, it gave me enough questions to actually practice the concept I just learned. Being able to practice over and over again, with fresh questions, on the test at the end of each segment was the best part. I'll use it again down the line.

The Accuplacer test went well. I was aiming for intermediate algebra so that way I could go straight into statistics for my nursing program. I scored 267 on next-gen quantitative reasoning, algebra and statistics along with a score of 241 in next-gen advanced algebra and functions and placed perfectly into statistics, so thank you again. I believe all of the word problems on the website helped. Any standard graphing, algebra, or geometry questions that came up on the test I was able to solve without much difficulty. I’m coming from graduating high school in 2011 and I have been out of practice with math.
Quinn Martin

I started using MathHelp because I was going to take a placement test to go back to College. The test went really well. My score on Quantitative Reasoning, Algebra, and Statistics was 274 which is very good for the Next-Gen Accuplacer test. The lady at the College said it was the best score she had seen in a while. I have nothing but to thank MathHelp for the review and the very well structured and easy to follow classes, it really helped me. I'm starting College Algebra this upcoming Spring Semester and will definitely come back to MathHelp in case I need some outside help.
