I'd give it more stars, but, sadly, when I started the specialization, the professors were very responsive and active in the forums, giving help and guidance.

However, more than a year after the specialization started, (this is the fifth course), the professors were totally absent, precisely when I needed their help!

I hope they'll be back or assign someone else to answer the questions of the students in the forums.

I have finished the specialization. The first 4 parts were more or less useful. Unfortunately, Advanced Algorithms and Complexity is a poorly implemented course. Some interesting assignments but lectures are pedagogically lacking (e.g., the Simplex Method isn't covered at all).

Inadequate student and teacher participation on forums, leaving students to figure things out without assistance or collaboration. Insufficient explanation of math concepts required to fully understand lectures.

This course is way harder than the prior ones in the specialization.

Took very long time fro me to be finished

Lack of support from teachers and incomplete explanations
