Flagging topics is now referred to as Marking in the Firecracker app. Based on user feedback, we've introduced three levels of priority for Marked topics; Urgent (for what you need to master right now), Current (for what you're studying at this time), and Past (for classes you've already finished). We also now allow you to Mark entire subjects as Past or Current, so you don't have to flag each topic individually. We recommend using the Urgent mark sparingly, for example, when you have an in-class exam upcoming for a topic. You will see Urgent material first in your recommended quizzes, and Current material will be prioritized above Past material.
