Resources for self-studying AP Chinese?

Next year I will be self-studying AP Chinese and am wondering if you guys could give me some tips and the resources you used to get ready for the test. My family speaks Chinese, and I’ve gone to China multiple times. My speaking is mediocre (in comparison to real, fluent Chinese that would be spoken in Chinese), my listening comprehension is pretty decent, and my Chinese typing is good. However, my reading skills are rather lacking in my opinion- when I peek over my mom’s shoulder while she’s reading something from wenxuecity.com, I have trouble recognizing a lot of things.

Thanks for the help!
