I asked similar earlier, [u][i][b]AS I UNDERSTAND IT[/b][/i][/u] (and therefor probably wrong): While the actual classes are going to be downplayed except for background plot devices, everyone has different classes in standard 1 hour periods to promote normalcybut you are at about a 60% likeness to have at least 1 person from the team in each class. The danger room demo probably only took 15 minutes to 30 at 7:30 in the morning. that puts us at 7:45-8AM at current time of posting. 
Some schools start between 7-9 AM depending on different rules from state-to-state and keep the kids on an average of 6-8 hours. This is because each state is required by law to have a certain minimum of educational minutes per year to be called a 'school'.
I'm doing a colab with [@Princeofhearts] for 1st period American History with professor Finn and [@shard]'s Casper is slipping into mutant social studies for 1st period as well.
