Super helpful. I tried other tutors and none went as in depth as him. I actually developed an understanding of the calculus I was doing, and it helped build confidence throughout the duration of my calculus course. I would 100% recommend him to any of my friends struggling with math.

I have never been good at math throughout my entire life. I have dreaded it, hated it, no matter what tutors I got I just could not do it. The math man completly changed the game! I have passed three semesters of math with A's from the videos alone! Thank you so much!

By far the best math tutor I’ve ever had! I thought college algebra was a lost cause, but after I contacted Mr. Blue, everything finally clicked. His streamlined note-taking methods and recorded tutoring sessions made a huge difference, and I earned A’s in MATH 117, 118, and 124. I highly recommend his services — they’re absolutely worth it.

Highly recommend! The tutoring was really helpful and having the full session recorded, along with the notes for each problem, was great for studying!

I am writing to express my sincere appreciation for this invaluable resource for AP Calculus AB. This is my first time exploring the site, and I feel incredibly fortunate to have free access to such high-quality materials—especially the multiple-choice questions (MCQ) section, which I have been searching for quite some time.
Thank you so much for providing these resources. Your generosity is deeply appreciated, and I wish you all the best. May God bless you!
With gratitude,

Blue is the best!
I was taking an online calc course that was very fast paced because it was an 8-week course. Even after countless hours of studying and using chat to explain the material it wasn't until I started sessions with Blue that I was really able to understand the concepts. He is able to record the session so that you can review them again later. The help I received from Blue was worth every penny and I would definitely recommend reaching out if you are struggling.

Words can't fully explain how amazing Blue is. Math has never been my strongest subject, especially online, but Blue helped me not only pass two math classes but also earn an A in both, with four weeks left to spare. I tried getting help at the math center, but their explanations were nowhere near as clear or helpful as Blue's. I would say it's worth every penny, and if I could, I'd take all my math classes with Blue!

Mr Hovatter truly is an incredible tutor! My daughter had some serious health issues this semester but wanted to continue with a full course load. Tutoring with Blue allowed her to do that. She said he is absolutely the best math teacher she has had. He explains things clearly and provides the right amount of support as students practice the problem/skill. Very thankful we had him for help in college calculus.

Blue helped me get through MATH120, even with the annoying textbook! I would recommend him to anyone taking a math class at CSU! Very great and understandable teaching style!

I would highly recommend Blue for any high school or college student struggling in their math class, and I wish I had known about him earlier. He is able to explain problems in ways that are easy to digest, especially for those who aren't naturally gifted at math. I also enjoyed working with him because he offers 1-on-1 tutoring, which is very helpful for the times I felt confused in my 300 something person lecture hall, as the professor obviously doesn't have the resources to give that much attention every single student in their class. Some important things to keep in mind before booking with him: he works with you over Google Meet, he charges $75 per session (each session is one hour long), and he only tutors up to Calc 1.

Blue helped me increase my grade from fail to pass. He took material he was unfamiliar with, learned it and explained it in such a way that I was able to comprehend. Truly Blue is a master of his craft and I cannot recommend him enough.
Santiago M.

Finished the course I was struggling on in 3 weeks and got an A. Super helpful and you learn everything way faster because of Blue’s teaching method. 10/10 experience.

I just saw him for the first time, didn't even get through the whole hour (my fault entirely, location problems), and the entire 117 unit 3 that I've been tearing my hair out for weeks over is naught but a pebble beneath my feet. Patience, Prudence, and Perspicacious. 10/10 would recommend and I *will* be using his services again.
Keane P.
20:17 14 Oct 24
Blue has helped me tremendously. If not for him, I am absolutely certain i would not pass math 118 or math 124. If you're doing the CSU online math courses, you should definitely consider getting this course.
Blake L.
18:34 18 Apr 24
He broke down both the math courses that I was taking (Math 124 + Math 125) so that I could understand the courses much better. I really appreciate all that he did for me this semester. Thanks Blue!

Best math tutor ever. I would be completely lost without the guidance of these videos and tutoring sessions. I would like to mention that this tutoring was mainly the reason I completed the course with an A. Thank you so much Blue, you are the best.
Jan H.
19:45 29 Nov 23
He's the Math Man for a reason.
Duh O.
00:32 20 Nov 23
Blue has probably been one of the best math tutors ever, I was completely stuck on math 126 and was afraid I would have to drop the class completely. That was until blue cam around and helped me, his teaching style is amazing and explains so many skills and abilities that can be applied to the math that the original course doesn't teach at all. If you are struggling with absolutely anything within the realm of what he tutors, I would 100% recommend him.
Virginia P.
22:08 06 Aug 23
Blue is all everyone says he is. My daughter was avoiding Math 117 and 118 and has significant math anxiety. He met with her privately for 117 and she purchased the videos for 118. She made it through both of them successfully. He really knows the CSU math program and all the ins and outs. You can't go wrong following his advice. He is patient and a great teacher. Thank you Blue!

I cannot thank Blue enough for helping me through Math 117, 118, and 125. I have always struggled with math and never scored higher than a C in math. Thanks to Blue I got an A in all of my math courses at CSU. Not only was he a major help during tutoring sessions, but he was also readily available to answer questions over email. If you are struggling with any math course, I highly recommend booking an appointment with the coolest math man!!

First off, if anyone is coming across Blue and thinking about using his tutoring services, I can say you would not be disappointed. I was recommended by a friend who knows Blue to seek his services because I was not very good with math, and I needed CSU’s precalculus requirements. I put it off through MAT 117, 118 and believe I only passed those classes because I was lucky enough to be one of the few who could take those in person. MAT 125 was a different story. I had to take that solely through CSU’s abhorrent excuse of math instruction. This time, I got access to Blue’s videos for MAT 125. They are easy to understand, cover every single question you are going to see on both the review exams and unit exams. What’s more, each question is broken down into what you need to know for the problem and the easiest method. If you compare them to the “videos” the CSU math department provides, Blue’s blows them out of the water. He will teach you only what you need to know to solve the problem and how to utilize the calculator to do the heavy lifting.
I am super appreciative of his help and believe anyone who uses his services will succeed.

I just finished my last math semester at Colorado State University. I
can not thank Blue enough. His videos got me through 3 math semesters. I really dislike math, and I have always struggled, but his videos made every step and every unit
understandable. Blue is knowledgeable about CSU’s academic expectations and
taught exactly what I needed to know to get through. Blue, Thank you! Thank
you! Thank you! I highly recommend you and your videos.

The best tutor I’ve ever had! He knows how to teach better than any teacher! He got me through math 141 with extremely little effort because I understood 100% of the weeks information within a one hour session. I ended the class with a grade of over 106%!! I got 100% on every test and every quiz. Plus extra credit on every test. The class got extremely hard week two and that’s when I decided to hire him. From then on the class was a breeze for me.

I pushed off calculus until my senior year of college. Math was a different language to me. With the help of the one and only Math Man, Blue helped me understand math in a way that no other teacher, professor, or tutor could. For once I found myself doing really well in math class. With Blues help not only did I do well in calculus but I was able to spend more time on my other classes. His methods are exactly what you want. I could not recommend a college math tutor more. The Math Man is your answer if you are struggling in college level math courses. Thank you again Blue, you somehow made math fun.

Blue made the PACE math classes a breeze! He teaches you how to use the calculator to your advantage and explains everything in very simple terms. I cannot say enough good things about Blue! He helped me earn 2 A’s in the PACE classes and I wouldn’t have been able to do it without him!

I did tutoring with Blue while taking a summer course of business calculus at Texas A&M. The online meetings were very helpful, and he was able to write on the same screen as the material while explaining easier ways to do complicated math. Overall his tutoring made a difficult and fast-paced class much easier!
Roy C.
16:42 09 May 22
I am not a person who sugarcoats things and Blue was an awesome teacher! His assistance with Algebra 2 was the only reason I passed the class. He was patient and always had at least three different ways to show you how to work something out if you didn't get it the first time. In addition, his methods of teaching were far superior to the curriculum I was using, but he was able to take that curriculum and work with what he was given to make it work for me. If you are on the fence about working with Blue, I encourage you to give him a try.
Caden B.
16:10 06 May 22
He explained everything very clearly and I was able to pass tow math classes in one semester because of him!!
Hayden A.
19:06 04 May 22
I wanted to keep this short and simple. I was heavily struggling in my 3 math classes I was taking. I quickly fell behind and didn't know what i was going to do. Thats when I found Blue. Without a single doubt in my mind he saved me more times than I would like to admit. So if you need help go to Blue and he will get you back on track in no time at all.

Without Blue I can say with confidence I would not have passed Matb 155. I have not taken calculus before and he made me understand it much better than my own professor. With his help I was able to get a B in this class which is a huge accomplishment. Thank you Blue!
