Well at my school there are these SOL's which are like state-wide exams you take in certain classes. If you pass advanced (90% or better) you get exempt from your final exam and your exam grade gets replaced with a 100%. If you just pass (60% or better) you're just exempt from your exam and its grade doesn't count. I've taken an SOL in chemistry and algebra 2 and the AP Euro exam so far, not sure how I did. Still got English, Spanish, Trig, Graphic Design, and Driver's Ed exams in June :(
