Cmv: grades are an accurate reflection of intelligence:
Certainly, you can be very clever and have terrible grades, but at the same time it is not smart to do poorly in school, thus limiting your opportunity. 

I almost get angry when I hear someone say this. Granted this is a blanket statement, and doesn't include outside circumstance such as extreme poverty or a disease, but I feel that 90% of the time laziness is to blame. 

I've heard the "I know stupid people with good grades" argument and I don't understand that. Even mechanically applied knowledge is still knowledge

Please change my view!
