Here's my junior year schedule:
AP chem
AP Bio
Pre-calc H
AP English
USH
As you can see, history is my only non-weighted course, and hence, my easiest class. But then I'm more of a science person than an English/history person.
Note I go to a pretty intense high school (in the top 50), so the AP courses can be very challenging.
The AP bio test itself was changed this year, it focuses way less on knowledge, more on graphical reading. It's like the science portion of the ACT.
However, I will tell you that 95% of my friends took APUSH. Although history is pretty much memorizing, for the AP test itself, I need to remind you that you have to write 3 (I think) essays in about 2 hours. This includes reading 10 different documents and synthesizing an analysis of the issue.
AP bio also have free response section (FRQ), but you are not graded on grammar or spelling.
I'm naturally good in bio, I basically got ALL A's on every single one of my tests throughout the year.
Because you have to answer about 80 questions in 55 minutes and write 3 essays in 2 hours, I suggest that you do NOT take apush. There's no way at your level you will be able to do that. I had to write 3 essays for the AP English exam, and it was horrible.
But seriously, if the only reason you are taking AP classes is so you can save money and don't have to take it in college, you will not do well in the class. GPA is only 1 component of getting into college. You can have a GPA of 100 and still won't be able to get into any good colleges. What you do OUTSIDE of school matters more.
Oh and download Google Pinyin so you can type Chinese.
You go to Mills High?! Lol... That's a pretty good school.
