I loved this course! It is unlike any I have taken before. All courses in this specialization have always included fun activities to make the taught content fun and understandable.

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.

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.

The instructor tried their best to explain difficult topics like cryptography to make as easy as possible. For this, they really deserve great appreciation. It can be improved if they did not just read out the slides but explain them in some places.

It was a great course, however it got really tricky at the end and I couldn't catch some mathematical concepts very well since English is my second language. I hoped there was more numerical examples before proofs.

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.

Some of the material is a bit hard to follow at times, but it's quite interesting and the final Quest quiz is a nice and fun way of putting everything together.

Great introduction to number theory, with little to no assumed knowledge. Proceeds quite quickly, but remains relatively simple and introduces concepts well.

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.

It was a great course which helped me learn number theory and introduced me to Cryptography.
The teaching assistants could have been more active.

It was good, one needs an advanced level of python coding to get through howecer the final assignment I enjoyed quite a lot.

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

The last week of the course makes everything else in the course so worth it! Had a great time doing this course!
