The course was good, the videos were informative and I learned some very useful stuff. HOWEVER, I was very frustrated during the quizzes. It happened very frequently where I would select an answer and click "next question" and it would think I was trying to skip to the next question when I had it answered! And if I refreshed the page, it would take me back to question 1! One time it happened when I was on question 8, it took me to a page that told me I got a 70%, and it made me do the whole module again. I thought it was a connection issue, but my internet's fine.
