It's a solid course. The structure is logical and most of the examples were helpful. Could use a few more real-world scenarios though.

Couldn't have asked for a better learning experience. The flow of information was excellent and the practical applications are already proving useful.

Decent material and presentation. The flow was mostly intuitive, and the applicability is there. Could be improved with more varied exercises.

Learned a good amount here. The examples were relevant, though I wished there were a few more practical application tasks. Still, a worthwhile experience.
