I don't know, maybe I'm wrong but the course was unnecessarily extensive, I came here to learn Java, not cryptography, Only content you'll learn about Java is ArrayList, HashMap, and HashSet which would take you one hour to learn in total, But because of crypto stuff, I finished to course in more than a week and got really tired. I think that was completely unnecessary and a waste of time.

The course asks for lots of programming and hard work which I appreciate as a way of learning better. But, some of the quiz questions have questionable wording which leads learner to answer wrong and have less grade even after knowing about the algorithm well and having correct program developed. This is frustrating.

Felt this was too vague for beginners, and too simple for those with experience. Spent a lot of time fighting with the quizzes to get it the answers it wanted, rather than focusing on writing good code.

Fantastic course. Great assignments and lectures. Low score because the workload is excessively high and overwhelming for novice programmers

Please, focus on what you want the student to know from the course. You exaggerate a a lot explaining stuff.

Some of the links are broken, the resources at some point are not found, and some of the exercises are vaguely explained ,considering the videos that are shown before each exercise.

Not really useful ~ I would like to email in a PDF of my comments covering this course and the second course in this series

A Very Hard course that you can't overcome it easily

The course is very poorly designed for begineers

Not useful content added for understanding

Not good
