50 hours per week for 50 weeks per year for 4 years is 10,000 hours

Or for most students, 40 hours per week for 16 weeks per term for 2 terms per year for 4 years is 5,120 hours.

Which might just explain why students coming out of college tend to be at most half good at something.

40 hours per week? Sure, maybe if you're a total conch.

For me, undergrad was more like eighteen hours a week for fourteen weeks, then fifty hours a week for one week. And that was with a heavy physics/maths courseload.

I was trying to be generous. Some students come out of college nowhere near to being half-good at anything. ;-)

Grad school will give you the other half. But: Beware premature optimization. ;)
