Yes and no. The content of the exercises, the discussions in the forum, and the topics of the live office hours will be tied to one another, and will reflect the most recent exercises.
But no one is forcing you to do the exercises along with everyone else! You can skip exercises or do them later. The forum and office hours recordings will be available for you to use, watch, and review at any time, forever.
I developed WPE to help you start learning Python in the most efficient, effective way possible. And it should only take about an hour each week, which is a very achievable time investment that will yield huge benefits for your career (or other Python-related goals).
