I’m class of 2006. Dropped out of my senior year, and transferred to a one on one teacher basis through a charter school. Still got my Highshool Diploma. Currently putting my self through community college with the aid of the U.S. Government. About 70% of the people I was associated with in high school took the AP test as it is recognized on a scale basis of 1–5 by colleges. Trust me on this, if we had the internet hot and rolling in 2006 like we do now, I’m sure studying for “world history” and “chemistry” would be a breeze. Back then even Wikipedia was sketchy, now it’s pretty clean (as far as the sciences and history are concerned). Still I would venture into a library and check out an AP test prep book and see what they deem important in world history and chemistry. Just a reminder though, world history high school classes are biased in the sense that its published by western society, so don’t eat it up for what you read, try getting a point of view of eastern society as well, to be truly informed. Also to sum this all up, my friends have gotten into UC’s (University of California) by taking the AP tests, so they definitely help out, it demonstrates that extra effort! Good luck! Knowing what I know now, I will encourage my child in the future to take the tests.
