Skating by with A's and a few hand picked B's is cakewalk for those who put in the effort to turn in papers and assignments and show up to tests.
Really? You think anyone can simply skate through college with A's and B's just by turning in papers and showing up to tests? For some of us that aren't gifted with an IQ of 140, it actually takes some work to learn linear algebra or basic electrical engineering principles, for instance. I attend a private university in the States and it's a metric fuck ton of work, in my opinion. I work hard for my B's.
Whom the gods would destroy, they first teach BASIC.
