Loads of AP Courses! HELP!

Hey people,
I will be a Junior at my local High School, and I was looking if any people could assist me in my endeavors of achieving good scores while balancing my large plate of extracurriculars. Time management tips are very welcome. I was also considering self studying in AP Psychology, but I doubt that because time will not likely permit me to do so.
The APs I will be taking are:
AP Calculus AB
AP Physics 1
AP English Language and Composition
AP United States History
AP Chemistry
AP Spanish Language and Composition
