<p>It’s not an odd thing at all to worry about!
I can tell you that, as a freshman, at least 3/5 days of class will start no later than 9 (Humanities lecture). I’ve heard of a Calc class starting at 8, but there are afternoon sections too.</p>
<p>EDIT: Of course, he could always skip Hum lecture if he needs the sleep (they inform the readings, but he’ll get all the info he needs from conference).</p>
