In course overview page, week 2 (also week 3) quiz and programming assignment headings are prefixed with a lock icon. Mouseover says “This item will be unlocked when you enroll in a schedule.” I’ve been able to Google up nothing related to doing that. So I’m stuck.
By way of disclosure, I did accidentally complete all of week 3 (including quiz and program submission) before starting week 2. Am I being punished?
Help, please?
