Self study 2 courses?

Test Preparation
1

Hi Everyone! Hate to be the typical new poster, but here I go.:)) This upcoming year is going to be my junior year, obviously the most important to colleges. For my planned courses I have:

  1. AP English Literature
  2. AP US History
  3. AP Environmental Science
  4. Honors French
  5. Honors Pre-Calc/Trig
    6)Ceramics

Additionally on the side I plan to self study two courses; AP Psych and AP Comparative Gov. Is there anyone who could offer advice on self studying 2 classes at the same time, on top of a fairly rigorous schedule, or people that have self studied either class and have some wisdom for me? Thanks as always!
