How do I set up a practice session with 10 MC (10MC)?

You can do the 10 MC by setting up a practice session by clicking on the "Practice" link in the header and filtering for “Math - Multiple Choice” in Section. Check off all of the Subjects that you're comfortable practicing with, set the Difficulty to “Adaptive”, Question Pool to “Unanswered”, Number of Questions to 10, Time to “No Limit”, and Mode to “Practice Mode”. For example, if you've only reviewed integers at this point then I would narrow your practice to just that subject, but later on feel free to widen the scope of your practice. I hope that helps! Please let us know if you have any further questions :)
