I was really impressed especially with the RSA portion of the course. It was really well explained, and the programming exercise was cleverly designed and implemented. Well done.

A good course for people who have no basic background in number theory , explicit clear explanation in RSA algorithm. Overall,a good introduction course.

In general, this course is much better than the previous 3, and I enjoyed all weeks but Week 4. I think Michael Levin should improve his explanations, and also try to give further examples about the algorithms he is talking about. I would say that it is worthy taking this course, but I really hope Week 4 can be improved.

Generally pretty good. Pretty easy level, and the maths is undemanding. Some imprecision in the wording of the tests, and a little too easy on the programming side, but well worthwhile if you still have some holes in your understanding of the principles of RSA encryption.

The class was interesting but I felt it was difficult and not explained well...to do the modules I had to constantly go back and re-read the slides, re-watch the lectures. There weren't any examples, I feel it would have been helpful in order to grasp the material.

Final week is a bit rushed, think it would have benefited from being one week longer.
Nevertheless, an excellent introduction to an extremely difficult and complex subject.

Amazing course, learnt a lot. The assignments were a bit difficult [ and time consuming ] but they helped me gain a better understanding of the concepts.

Good material and presentation from the professors. Programming exercises were a bit confusing at times. Overall, short but mathematically solid course.

Sometimes material is very dense. Watching in 1x speed multiple times advisable for some modules later in the course.

Great course, just felt that the last quiz was a bit redundant.

The quiz from the RSA segment is a drag. The reason is that I don't see the implementation of the "given" functions and debugging via the text box provided is annoying. The first 3 segments are well prepared and have enough information for someone like me to pursuit this topic further.

very confusing explanations. had to look up everything elsewhere.
