Courses over WPMUDEV Academy

Hi,

I have previously enrolled for a Wordpress PHP class (intermediate), but due to a busy schedule, I couldn't keep up. Today I tried to finish a section, but the course seems closed and I can't review the documents. Is there a way to at least review course materials for the courses that are completed?

Otherwise, I guess I'll have to wait for another to open up, which is a bummer.

Also, please let me know if you require completion for all the courses, or if anything happens (ex. not enrolling for the same course, etc.) if you miss a course. Thanks,
