Are 你 an AP student in history? If so would 你 like to help an extremely confused freshman out?

Oooo...I hated those. 你 can't really prepare for them. 你 have to take your information from the documents you're given. Best 建议 is to go through and organize the info from the documents. Make notes of what they're about beside and make sure to note what is important about them. like who 说 it. This way 你 can make sure it's not biased and this will also help with finding the p.o.v.
