Good and practical training approach to solve real worlds problems. Assignments and quizzes are quite challenging and interesting. Greatly motivates us towards programming and problem solving skills.

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

Maybe this course for me are the most difficult, but the teachers, the teaching method and the spirit of Coursera in the mate´s class are the best.

6th question in final quiz is really hard for non native english speakers. Please avoid questions with multiple selection and with lots of text.

Some concepts used in Week 2 were introduced/ explained in more detail in Week 3 so I struggled in Week 2 but Week 3 was a breeze.

Useful and helpful, a millstone in the specialization path, but not so preferable if you only enroll this single course.

The final quiz has 3 difficult questions for which I could not find a good answer. Luckily my guesses were good enough.

Hope the mentor can be more responsive on forum, as the quiz is getting tougher and need more help on it

It would be helpful if explanations of the problems in the quiz were made available after passing them.

This is a very good course for the price, assuming you are at the beginner level (like me).
