Closed-book fallback card for day 90 when you are not using a separate kit realtime card. This file is the interviewer. It is not a worked example.
Do not open chat or live-video lessons while this timer is running. Do not scroll past the attempt barrier on the day 90 page until you have scored. The interview kit is optional; this card is enough.
