An add-on that adds a blue "before exam" button (shortcut: 8) which marks your card as "good" and schedules it for a random day between tomorrow and your exam, so you'll be guaranteed to see that card again before your test.
This add-on also highlights the "again," "hard," "good," and "easy" buttons in red if the card will be scheduled after your specified exam date.
Set your exam date or toggle on/off either of the features by going to Tools > Before Exam... Note: the Before Exam button will be greyed out if your exam is scheduled for tomorrow!
Disclaimer: I asked Claude Code to make this add-on for me!
