You can search on "grades" or "spreadsheet" to find some info. See if you can find the pieces you play on some of the lists. Be aware when you see various lists of graded pieces, that there are several different organizing systems; ABRSM (British) grades are different from RCM (Canadian), which are different from Australian (can't remember what it's called), and so on. (The ABRSM website has their syllabus online, I think.)
Or ask your teacher. But as far as I can tell, there is no coherent system in the US, if that's where you are.
