I gave 5 stars ....should have been 6 or more!!!!.....a Masterpiece of course.....Thanks Dr Ghrist, really thank you for it.....and congratulations to you, your team and all who study it....

This course is highly interactive. You'll never experience boredom. This is recommendable to learners of standard level. Remember you should have at least studied calculus at high school.

I learned a lot from this course.With animation to explain the formula,makes it easily to be understood.The learning of calculus laid the foundation for my future study.Thanks,professor.

This module is great. The thing I like most is how professor implements the theory into Physics and other realistic models. Ive also begun liking statistics a little bit. Now, part 3.

I love this course, and it's really interesting and practical. This time around I had 79%, and this is the second calculus course I took with UPenn. My third one will be around 90%+

The course changed my view on Calculus Study, especially Differentiation greatly. This is a fantastic course. I like the Powerpoints very much as they look attractive.

Great, really good. Again great videolectures, great examples, nice bonuses.

I think I mentioned this but again, great videos, the colors, the clarity. Thanks.

W​ikipedia, Lang's calculus textbook, and the course notes from the internet archive were my constant companions. The homeworks certainly got me to study!

This is, by far, the best course I have ever taken. I will take the Multivariable Calculus course when it is open, after finishing the 5 S.V.C. courses.

Very nice course. It served as a good refresher, and was not hard for me. The material is presented in a different way than a typical college course.

Explanations are crystal clear, with a strong emphasis on developing a deep conceptual understanding of math rather than "calculating derivatives"

Great course. Even if you know differenetiation you will still find some useful information you didn't know about it. Let's go to integration ;)

It's an awesome lecture. I strongly recommend to take the course in order to improve your understanding of Calculus, especially differentiation.

Excellent! I really love this course. The Professor is awesome! He succeeds teaching the hard course in a easily understandable way. Great!

F​antastic course. Really well prepared by the professor. Please check out his website and youtube channel. Very well worth it.

Very interactive videos, gr8 co-learners as the forums are full of methods and new ways to approach problems...

The quality of Professor Ghrist's lectures is just wonderful. It is a joy to study this course. Many thanks.

This course is good because there are challenging questions which helps you apply the concepts in calculus!

It was a brilliant continuation to Course 1- Functions, very thoroughly explained. I enjoyed this course!

I liked this course very much. The lessons are clear and interesting, the exams challenging but feasible.

It's very good for me to start a new way to the math and it opens up my new ideas, thanks to professior G

Great refreshed on calculus. Gives not only the theory, but builds an intuitive sense of it all.

Recommended also for people who wants to review the topics after passing this subject in College!

just excellent, please make one on linear algebra, discrete mathematics and multivariate calculus

Gives a new perspective on derivatives and the clear insight into how a simple calculator works
