Here is the schedule for the 4th quarter. You can finish the sections any time before the due date as well, so you don't have to wait until that week. I think this will be the final schedule, but The Khan Academy is adding mastery subjects all the time, so I will let you know if there are changes.
Good Luck, don't wait until the last minute to finish.
