Awesome course but not for the light hearted Incredible course on single-variable Calculus but not for the light hearted. Presentation is both entertaining and enlightening. It's as if professor Ghrist has this extraordinary ability to hypnotize the audience into understanding difficult concepts as simple and straightforward. Awesome artworks. Forum, homework, wiki and the level of student participation are all top notched.

Can't wait for the multi-variable calculus follow-up course.

Great course, very challenging Viasually attractive and quite humurous, this course is a great ride. Even if, as myself, you start to feel like you can't keep up with the level at times, you are bound to get a lot out of the experience.

Demanding course for people who want to gain deep understanding of calculus 1. It is a unique course in terms of content and presentation style. As person who has taken a lot of MOOCs and peeked into even more, I must say that this is an absolutely unique course.

2. It is extremely demanding (in fact, I end up spending 10-12 hours a week), but with hard work it can get you from "I sort of remember some calculus concepts" to a mathematical prodigy, seeing math all around you (including your dreams!). If you're in a sweet spot in terms of your level of calculus, you can gain A LOT.

Note of caution: do not enroll in this course if you're not prepared for spending at least 10 hours a week. Do not enroll in this course, if you remember nothing of integrals, differentials and limits, otherwise it will turn out to be terribly frustrating.

3. Even if you already know calculus quite good, you can take from this course deep (and enriched with visual examples) understanding of many concepts, and also learn a lot about applications of calculus. Every lecture includes 'Core' homeworks, recommended for everyone, and 'Challenge' homeworks, suited for people with advanced knowledge (or perhaps for those willing to spend couple of extra hours trying to tear apart advanced concepts).

4. Professor Ghrist (or prof/g for short) has amazing skills at presenting material. Seriously, I bet he spends days to prepare each 15 min lecture piece. As a result, they turn out to be densely packed, highly comprehensible and very visual. Although I sometimes spend an hour to get through 15 min lecture, I very rarely feel that I didn't understand something from the lecture. His teaching is very clear. So I also recommend this course to anybody aiming at creating a MOOC or just teaching students. In my opinion, it is a great example of how it should be done.

I have a good math background, albeit rusted. Enjoyed this course very much. High quality, conceptual, clear, and interesting structure, presentation, and topic coverage. One of the best on-line course I have ever taken (a couple of dozens).

It is not work, it is fun. Well, almost! This has been by far the best math class I ever attended. Prof. Ghrist shows outstanding skills in explaining complex things in an easy-to-understand way. The provided documentation, slides, and video lectures are really awesome. I thought intensively about it, but I really can't find anything I dislike.
