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.

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!

Extensive coding skills and a thorough understanding of the key concepts are needed to pass this course.

Slide and instruction could use more concrete examples, but final project was excellent.

It was really slow in the beginning, but I loved the RSA Quest!

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

Some of the questions related to week6 did not behave properly

a really starter for cryptography!!

In all honesty, this was my least favorite course in this specialization so far. Alex and Michael did a great job with making interactive lectures in Graph Theory, but for some reason, the Number Theory lectures were much more textbook-like recitations. There were certainly times in the lecture when I felt like I would want to see them on the whiteboard. There were also times when critical steps of a proof were not really emphasized (or on the slides at times) and it was very confusing. I spent a lot of this course supplementing with MIT OCW lectures. All this being said, the final RSA quest assignment was awesome; it's clear that the profs had a really fun time putting it together and it showed. Thanks!

The lectures are not always clear enough. Somtimes the explanations in the speech of the formulas are not accurate enough and it will be better to add more formal explanations with letters.
i don't understand why during the course the staff did not answered to some of my questions from the theoretical material although I paid twice for the course.
I left 6 unanswered questions in the fourth week in the forum. I hope that the staff will answered them.

The concepts taught are honestly pretty interesting and i enjoyed learning the content. However, there were some parts of the lesson that you wish an example would be given for clarity, e.g. explanation on RSA. Also, don't expect much help from the discussion forums by teaching staff as reply rate is slow. Lastly, debugging for the RSA codes are pretty limited, so do expect more time spent! Overall, still an insightful course for an introduction on Cryptography.

The course was fun, the final assignment was really interesting. Python programming is mandatory for anyone who wants to succeed in this class. Nevertheless, I was hoping there is more mathematical discussion regarding cryptography. Some key elements, such as Diffie-Hellman key exchange and discrete logarithm problem are missing from this course. Anyway, it is still interesting though.

The course is good, the topics covered are nice. The problem is that they don't teach examples very well. The last few quizzes will be tough and it will be hard to complete the course if you don't have good coding skills. The topics are interesting, that's what made me stick to the course. Also the professor's accent is a little difficult to understand.

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.

Last chapter was way too challenging compared to the previous ones. I had a really tough time with the assignments. Otherwise, a very nice course !

The instructor sometimes rushed through the content.

Tough course for non-math
автор: Ishrar C•
needs more examples for the theorems. they emphasize on the proofs more than making us understand the theorems. otherwise, okay.
This module was the worst module in the whole specialization course. Lack of example, non-clear explanation, variables that are difficult to understand, weird way of abstracting the explanation. it feels like instructor abstract in a way that only to take student already have pre-knowledge to understand the course.
During the Euclid, It took me 4h on keep watching the videos and I found a single page that explained to me in 2 min.
Even I don't get the certificate for specialization I am not going to finish this module. From my experience, this Is a very good module that makes a person to hate to learn about number theory and cryptography
During the course, I thought only I was the one who doesn't understand what the instructors says but looking at the review I noted that it is not the case

This was a pretty rough course, Michael Levin knows his stuff but his style of charging straight through everything with variables didn't work for me so I would catch the title of the lesson and head straight over to YouTube. Examples of the concepts in action where the instructor interacts with the screen instead of just talking over powerpoint slides would be great because the content is legit but the instruction could stand a boost or two

After few lecture this course is just slides reading and no proper explanation.
автор: Samuel R S•
very confusing explanations. had to look up everything elsewhere.
