This is a very nice course. The teachers speak clearly and explain very well. The subject used to teach Java (cryptography) is interesting. Many thanks!Kind regards, Wim

It was very helpul in knowing the concepts of Caeser Cipher and how can we implement in our daily use.So that the information hacked by the hackers may get reduced.

Great teaching, great presentations, interesting and engaging problems, and great assignments that really test your skills. I have been impressed with this course.

Very difficult material in week 2. Took a lot of effort to get through, but was worth it. I am continuing to learn about Java and writing more fluid programs in this specialization.

This is my second Duke course, i'll take them all they are great. And i like the feel when i finish it. I'm still a student, i finish one course every two weeks.

Fun course, well-designed curriculum. Imaginative, real-world inspired assignments with just the right level of guidance. The instructors are skilled and personable.

Actually, before I start this course I had not a good idea about OOP concept such as constructors, HashMap.now I have fair confidence about that. thank you duke university making such an arrangement.

GK

The assignments were not clear and I didn't know if i should go back and use my Caesar code to get some of the answers for the assignment. it would be nice to hint a bit more

JA

Learned a lot from the course, but the amount of programming assignment and number of Qs to complete the module (especially week2) was absurdly large. Could be split into separate sessions.

Thanks to the professors of Duke University for teaching this course using Security and Networking related practical problems. It enhances my knowledge and will recommend others to pursue this course.
