3.8 GPA, My intelligence? it depends how you measure intelligence. There's more than one way to do it.
Also just because you have a high GPA,it doesn't mean much if you go against people who take AP classes as myself. I'm in the top 10% of my school and that's with dealing with personal issues like Major Depression. It does tend to get in the way. 2 of my childhood friends are #4 and #5 and there pretty smart at everything they do. The #1 guy, I had him for and AP class and just because he was 'intelligent' for being the valedictorian, it doesn't mean he was mature not an 'ass'
He was pretty immature, some people would consider that to be something an 'Intelligent' person wouldn't do.
Anyways, there's more than one way to measure someone's intelligence.
