I can't work late at night. After 18:00 my cognitive functions drop to almost zero and I fall asleep by 21-22. It's possible to shift this slightly if I wake up later, but most of the time it works this way.
This is why I have an hour and something like 10 minutes to study for today's test. We covered the material yesterday and classes lasted 'till 18:30 so there was no way I could revise. Anyway, time to study.
