Becoming a PA State Trooper?

I am in the middle of my junior year and i am currently thinking about the cles i am going to take next year. I really want to become a PA State Trooper. In addition to my four main cles (English, math, History, and science) what other courses should i take? i was thinking of taking Socialogy, would that help me gaining the education to become a trooper? After i graduate i was thinking of going to a community college and getting an ocates degree in criminal justice. What would i have to do after i obtain my degree to become a state trooper? Also is that the correct path in becoming a trooper?
