It's not really an accurate depiction because the schedule is very different every day, but rather an over-all averaged example picture of weekdays. The course descriptions are all planned so we study presumably 60 hours per week.
If I don't make dinner I usually just eat oatmeal or for the past two days apples. so I avoid dying from oatmeal-overdose.
I think it would probably be nicer to trade some vacation away for less stressful weeks.
