Sorry if it's not appropriate for the forum, but I couldn't find another location to offer some feedback: The lesson on Classes is highly redundant with the previous lesson, Introduction to Classes. The same concepts are covered in both, and the second lesson is actually a bit slower than the one before it, in my opinion. Just wanted to flag this in case someone at Codecademy wanted to streamline it a bit. Thanks!
I could use the review and the practice. For some advance or fast learner/users (perhaps like you) it may be redundant. For ones like me, it's OK to go over the concepts and the practice one more time.
