Sadly, in this course the material was presented in such an oversimplified way and stripped of details that it was very difficult to develop an understanding of the concepts being presented. For instance, for curvature the instructor only gave us the formulas for computing it, but didn't say where they came from nor even gave us any intuitions behind them.

The first half of this specialization is ok and well balanced. But in my mind, this second half, specially since calculus, the complexity and practice of classes is umbalance with the complexity of the test. I run all times on trouble have to look for another sources to resolve the test. In other terms, the complexity scale, but the pedagogic doesnt.
