Interesting course on an Interesting topic taken in a pleasant, enjoyable, and simple manner.\n\nNever did I feel bored or out of my depth even though I am a stranger to the topic.
The lectures were educational, and interesting without speaking down to you. I learned a lot without being overwhelmed
I think this is the worst course in Coursera which I have taken. The lecture is very bad , only see the teacher saying from begining to the end, without prepare any animation and slides. I can not remember so much usefull knowledge about the Cryptosystem in the course, I should self learning a lot of things from the link after each course. The professor did not give me any more value but only some link from wikipedia.
