Wait, College requires you to be tested on how fast you can accomplish something rather then what you've learned?

For my 20% time i've been doing ACT prep after taking the Pre-ACT. I've started on the english portion and i've realized that i don't know a lot of words pertaining to the English Language. Who is going to describe someone as atrabilious when we can refer to them as cranky or grouchy. I understand the need for knowing a vocabulary but words that i won't use after school can determine whether i am able to go to college with a decent scholarship and being flat broke. I'll continue working on ACT prep but i'd rather criticize articles written in major magazines or news sources. Now all that stands in my way to a firm begining is a catchy slogan, hmm..
Peace out,
