Santilli is good. I had Calc3 before many years ago and was taking his course as a refresher. It didn't take long before I realized that I new nothing about Calc 3!

This professor is the best math teacher I have ever had. Toughloves are just that- TOUGH but probably necessary. His exams are fair but long. Homework and class notes are extra credit which is worth one letter grade. If you are willing to work, he will teach you more than you thought possible. I plan on taking him for MAT 231.

Professor Santilli is one of the best instructors I have ever had in any subject and I would highly recommend any one interested in science or engineering taking as much of their Calculus sequence as possible from him. Be warned though: this is not an easy class. You'll work very hard but, at the end, you'll KNOW this material very well.

I would recommend ANY class taught by Santilli. He's passionate about math, and holds his students to a VERY high standard. I got an A in calc 2 (from another professor), but I was really PROUD of my B in calc3 from Santilli. His classes will take over your whole life, but you'll learn a lot, and discover the areas you are weak. Brilliant.

Santilli seems to have an adversarial relationship with his students. The highest score on the first test was a C! As far as lectures go, he isnt that bad, slightly above average.

Santilli is NOT the professor to take if you are just looking for the credit and/or not planning on using calculus in your line of work. He crams a lot of info into his lengthy lectures.

Mr Santilli, his teaching standard is with no doubt "MIT-ish". You will start with a class of 40 ended with less than 10 passing the class. He gives a "Toughlove" 1 point 5 questions quiz randomly from his internet handout. His tests are extremely challeging. The homeworks are not mandatory, but this is where everyone slack off and fail.

My experience with Santilli made me a more passionate learner &amp; motivated me to do better not just in his class, but set me up for success through obtaining my Architecture Degree at ASU. Because he took the time to care for me as an individual, I had the positive push to do better in life. Disclaimer: Physics at South Mountain back in 1999 or 2000

WORTH IT!!! Santilli was/is the best out there. He's skilled in ways that go beyond any logical professional on this planet. He cares deeply about his students &amp; wishes to see them succeed, in life &amp; his class. He is tough but you'll thank him later for it. Ignore the bad reviews!! They did poorly in the class and are biased against online learning

Professor Santilli is my all time favorite professor. He challenges the class to do the work and think critically. He is knowledgeable well beyond Calculus and excited my curiosity for mathematics, physics and engineering.

To give a reflection of this class, I must say it is not a good class to learn in. You will quickly realize memorization is paramount when you take the &quot;tough quizzes&quot;. Their style is poor with emphases on memorization, little conceptualization, and poor explanations. Taking this professor is a waste of time, you're better of teaching yourself.

Lots of homework

He presents mathematics in the way that many other teachers can not. If you looking to challenge yourself to learn above memorization you are with the right person. I can only be thankful for all the hard work given in his classes. Michael Santilli keep his students out of the ordinary. Halan
