3 and 5, but I went with 5 because I hate waking up early and is faster and more comfortable to travel at those hours.
But the worst thing ever is to have classes on Saturdays... (happened twice)
Spoiler: My schedule
My schedule right now:
Mon 19:00-23:00
Tue 18:00-22:00
Wed 15:00-18:00; 19:00-23:00
Thu 15:00-19:00
Fri 18:00-22:00
I don't have much options to choose classes, and they are generally at night.
