Sample run. The score here is just for the demo.
You don't pick the questions. Lock In does, so you're not stuck redoing stuff you already know.
Ten questions, mostly from your weakest topics. Get three right in a row and you start earning combo XP.
Anything you miss comes back the next day, then a few days later, then a week after that. Three right and it's gone.
Your streak and the days left until your test, right at the top. Skip a day and the streak resets.
Each week you're in a league with your friends and classmates. XP only counts for right answers, so spamming easy questions won't get you anywhere. Finish top three and you move up.
