I'm 6 classes through it. Classes vary wildly in difficulty and applicability.

Favorites so far for me were AI4R (Ariticial Intelligence for Robotics) which is a more rigorous version of Udacity's Self-Driving Car course, ML4T (Machine Learning for Trading) where you implement various algorithms to optimize trading strategies, and ISYE 6501 (Intro to Analysis), which is a survey of various analysis techniques and ML algorithms.

Still have to take the reputed hardest course in the program, the General Algorithms course, the ML course, and an elective.

Worth the money, though I have had to skip a couple of semesters due to burnout. Work and this program are hard (for me).
