Good foundational course. Explained things clearly, but could have used more hands-on practice to solidify the learning.

It was a pretty good course overall. Some parts moved a little fast for me, but the examples were generally helpful. Worth the time investment.

Good foundational material. I liked the mix of theory and practice, though a couple of the examples could have been clearer. Overall a positive experience.

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.
