First off, that's one one of the more engaging courses I've seen. What stood out most for me was the different style guide (fonts, colors, themes) you used for each module.
Like others, I found the Quizmaker personality profile highly engaging. The combination of animated intros kept the pacing up and I found myself looking forward to the next question. I can't remember when 15 questions passed so quickly.
Nice touch on the image-thought cloud effect. I liked how the image preceded the thought cloud and then fit into place as the thought cloud slid in below it.
Build your jigsaw - Great use of fill in the blank combined with an effective progress meter on the left. Sure I could look up top and view the Question X of X--which you creatively titled Piece x of x--but the puzzle piece progress meter was great.
Opportunity awareness - LOL loved the warning sound & flashing light.
Opportunity detector - you created a quiz out of the Labeled Graphic - awesome! Nice touch with the "incorrect" buzzer sound.
Action Plan - yeah, one of more creative examples I've seen there, too
Well done Daniel!
