I thought the course was good. There were a few comments I had regarding the quizzes. Sometimes, they asked questions about material that wasn't presented yet. For example, I was asked about the blue and white Alpha flag and what it meant fairly early on in a quiz for a module that didn't cover this flag, and it wasn't covered until a later module. Also, I didn't like how I was unable to go back and see which questions I got wrong on the quiz. This course should prepare you for the test - so I should be able to see what I got wrong so I can go back and review that material further or understand where I went wrong. Instead, I was left not knowing and likely made the same mistake on the actual exam.
