All course on MongoDB University are unlockable. What it means is that you do not have to wait for any specific date to get access to the contents of the next chapter if you have done all the Labs in the previous chapter. The next chapter gets unlocked for you and you can make the submissions for labs and quizzes earlier than the default start date.
If you are done with the previous chapters then you will be able to make submissions for the final exam even before it’s start date - Dec 03, 17:00 UTC.
Or, you can go with the default dates and make submissions for the final exam anytime between Start Date: Dec 03, 17:00 UTC and Due Date: Dec 10, 17:00 UTC.
There won’t be any next slot for the final exam after Dec 10 for this particular offering in which you are enrolled. You must submit your answers prior to the due date which is Dec 10, 17:00 UTC.
Hope it helps!
