UCB Class difficulty

@ProfessorPlum168

Thank you so much again for your help!
My middle son is freshman at Cal Poly SLO,
and he has been taking 4 classes per quarter
beginning with the first quarter.

He somehow has been managing to get good grades.
He gets up at 5:30am to work out for 2 hours,
too.

He is definitely deciplined, but my oldest is
totally different.

I am just a worried mom, I know…
