This trick lets you skip the waiting period from 6am to 8am in the classroom every two days.

Setup:

1. Wait next to your bed until 9:00am.
2. Once the time hits 9:00am, wait about half a second, then press A to interact with the bed.
3. Go to bed early.
4. You will wake up the next morning, having skipped school.
5. Go to class.
6. The "I'm late for class" cutscene from the day before will play instantly.
7. Go back home and go to bed early.
8. Repeat step 1 - 7.

If you perform steps 1 - 3 on Friday you will be teleported to school on Saturday because the game thinks you are late for class.

Explanation: The game checks if you're late for school at 9:01am and the game won't let you go to bed early before 9:00am. This means that there is a small time frame where you can go to sleep before the game teleports you to the classroom. The game remembers that you are late for school but the cutscene only gets triggered if you're inside the classroom. So by entering the classroom the next day, the cutscene plays instantly.
