About what grade in piano is this?

this "level" system is based off theory knowledge. The theory book usually only goes up to level 10. There are tests for each level, in my state, they're called CM tests and require knowledge of theory books 1-10, and certain pieces and scales. After level 8 or so you are required to play an etude instead of a scale The test after that is, well atleast in California, is something called PANO or PANL or something, i forget. But based on the pieces you're playing, this is about theory level 7-8 (in California). Probably guessing you're a freshman in highschool too. wild guess.
