Well, my husband drank beer and played video games while doing one of the hardest programs in the Navy and graduated first in his class. His friends hated him for it, since he'd be calling out answers to them as they studied while he just played games the whole time.
He is getting good grades in his upper level college classes, too, now, even with watching the baby and playing the video games.
Different, I know.
If you are intelligent enough, you can get through undergrad (and law school) even if you are personally dedicated to having close to zero engagement with your classes.
The downside is that when you are actually asked to do things in a professional setting, your skill set is essentially nonexistent.
