Spagett+"I didn't do well on my ACTs and SATs so they are bad and I hate them, but trust me I'm smart"
I get what you're saying but it's not remotely what I mean. The fact that universities don't rank these scores as most important also agrees with my position. I'm more saying they aren't as good of a measure for how applicable someone can use their brain. I guess I'm old enough to see kids who did really well at their standardized tests drop the ball in real life applications.
Like Zoidberg above said, the GREs don't even come close to measuring your aptitude in your graduate field. If high schools actually taught kids how to write better, organize their thoughts in more coherent ways, and be able to orally communicate those thoughts better, then those kids are much better prepared for real life than kids who can memorize facts/stats and find patterns between 2 associated words.
Many people on here said they hated public speaking (there was a thread a month or so ago) because they find it challenging or daunting in some way. But, this is definitely the best way to get to know a subject matter- if you can clearly and cogently talk about a subject, then you will know it (obviously some subjects like math, logic, etc will be better written given their natures). If schools taught students how to speak about their subjects better, it would encourage them to know the material better than simply taking a Scantron test. In order to speak well on a subject, you need to know the subject well, and this skill is something the real world looks to more importantly than standardized test scores.
