COURSE IS VERY GOOD

I LIKED THE WAY OF TEACHING AND THE PROBLEMS IN THE HOMEWORK AND QUIZ SECTION

THANK YOU

Passionate, heart-felt teaching combined with challenging homework make this a course worth investing in.

Great course series to learn, thanks for the work of the staff! Hope to study Multi Variable series soon.

Extremely concise lectures. Good aiding graphics. The HWs are challenging yet doable. Highly recommended.

Very good video lecture. Very good speech for not native english students. But little difficult for me.

Good explanation of quite complicated things. Bonus materials are especially useful for understanding.

Wonderful lectures! Clear and succint! It would be greater if more application examples are involved.

This was very useful. Explanations were (relatively) simple and the quiz commesurate to the teaching

A very challenging course that makes the quizzes and challenges sweet and passing it even sweeter!

Growth of functions approach is somewhat more effective tool for reasoning than the normal stuff.

Great course. Really good videos and the exercises seem to be at a really good level. Thank you.

This was very explanatory and helpful. I would recommend it to many of my friends and colleagues.

Professor Ghrist is a badass. Re-ordering things to put Taylor series first is a brilliant idea!

I really enjoyed the course, it was very helpful to understand the Taylor series. Many thanks.

I like this course very much. Prof. Robert Ghrist is humorous, and the mentor is very helpful!

The course is perfect and the professor put all his effort on the program. It did help a lot.

It was really useful. But, the tests were very hard. I did enjoy this course. Thank you all.

I liked the difficulty of the questions. Very good course. Thank you sir for your hard work.

The course is rigorous. I managed to learn something about Big-O that I did not know before.
