The content of the course is highly relevant, but the assignment/quiz structure may not work well for all learners. Like the previous course in the specialization, lecture videos and screenshares from Doug Schmidt's college courses, optional assignments, and simple quizzes make up the course.
Your initiative to apply what is being taught is what makes the course worthwhile, and if you were to breeze through without doing the optional assignments, you may come away without absorbing much of what's being taught here.
On the other hand, if you take the initiative to apply these concepts to projects on your own, you'll be rewarded by the focused explanations in the videos and what you're asked to do in the programming assignments which are specifically engineered to make you use what's taught.
It's a great course, but requires motivation on your part!
