I HATE SCHOOL CURRICULUM REQUIREMENTS!. what do i do?

ok, i absolutely hate it, espesicially since they wont let me test out of the courses. Ive had an interest in mathematics and atmospheric science for the past few years. And being a nerd, I taught myself all of the required math and all of the atmospheric science the senior year of college level. im not smart or anything, its just that you can teach yourself the basics (that the schools waste years on) really fast. i really dont want to take 3 years of stuff that i already know, and thats what happened in highschool. i hate it, school systems are so ineffient they bore everyone to death. i taught myself calculus and trig just after finishing algebra 1 in 8th grade, while the school thinks its necessary to stretch everything out , algebra 1 is the same as algebra 2 pretty much..
