FYI, I am a lazy bastard, and spent the last two years of highschool getting shit grades and almost never doing homework or studying for exams, but I never got less than a B on tests, simply because I derived most of the exam problems from scratch or bits of memory, instead of studying and memorizing things like my classmates. Out of humility, I'd like to think that I'm not that special, and any one of my classmates could have done the same, but I somehow doubt that.
OK. I totally believe you have a 160 IQ now.
Seriously, the smarter you are it seems the more bored people are in high school. In my experience it seems those that have the best grades are the ones in the 120-130 range. I was just barely above that so my grades were OK but not great. I did not care that much. I was shocked when I graduated with honors. I was like, "How did I do that?" I was not really trying to.
I felt a little guilty then. I often think if I had only applied myself I guess I could have graduated at the top? But I did not care that much really. In fact, after taking one AP class I realized I was working harder for an "A" and it would be much easier to just take a normal class, not study at all and get an A or B. I guess I was a little "lazy" too. I always got shit grades in school, except that I was also in a bad financial situation and had to work up until 12AM as a waiter despite the fact that it was illegal to employ me that late as a teenager, I was also almost always tired in school and rumors were running around that I was using drugs, one of the teachers even told my friends not to hang out with me because he was so convinced, all the "geeks" that studied well in those days are lacking aspirations nowadays and generally behave like sacks of shit getting below-average pay and spending their free time being backstabbing lazy couch potato stoners, people that are like minded and go through life like sheeple taking advice from teachers/parents/friends go nowhere in life.
I ended up getting an awesome job with above-average pay, getting in shape, smashing sloots and generally having a pretty sweet life. High school grades != (Intelligence/success in life), Uni grades !=(Intelligence/success in life)
