The course is good

The problem is that a very high level of English is necessary

I have a good level of English but am spending more than twenty hours a week to go forward

Although I am computer training is costing me a lot this course

by Ilya completed this course, spending 5 hours a week on it and found the course difficulty to be medium.
Much more approachable course than those in Stanford (and even than Katz own book). Especially if you prefer top-to-bottom method. I've completed Stanford course 2 years before and it's great but now I'm really understand mechanics behind modern cryptography and all its proofs.
