When your friends take a qualifying exam, you should:
1. bake them cake
2. take them out for drinks after
3. yes, even if your own quals are the next day.
Furthermore, it is not acceptable to allow any member of your cohort to take quals without said cake or drinking, or equivalent celebratory/stress-relieving activities. Moreover, it must not be incumbent on the examinee to arrange the festivities.
