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 !

OJ system is not good and support should be better.

The instructor sometimes rushed through the content.

Tough course for non-math

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.

very confusing explanations. had to look up everything elsewhere.

Many errors, dificult to understand
