Hi Adelissa,

Most of the courses listed in the Explore menu will count towards your streak, but there are a few exceptions. To count towards your weekly streak, the course needs to be a mastery-enabled course. You can check this by looking at the home page of the course---you should see a mastery percentage listed there:

If the course does not have a mastery percentage, then it is not mastery-enabled and will not count towards your weekly streak.

I hope this helps!

Yall could do sience or algebra.
