The ordinary time table of Ivey's students is:
7:00 get up
7:30 leave home
8:00 first class
13:00 last class finishes
After class, you are supposed to spent 6 hours on case preparation, 1-1.5 hours on group study, 1 hour on club activities. And most of us need read text books. After that, how many time you want to use for eating dinner, doing laundry, going grocery, etc?

GMAT>700 does not mean good English communication skills. As a non-English speak, we must spend more time on practicing speaking & writing.
