I just finished my 2nd year at Case. Our class (2015) was the first to get letter grades as opposed to pass/fail. They switched because our boards are now pass/fail. Prior to our year, there was an unofficial record of GPA and class rank, but it wouldn't show up on your transcripts. Now all your grades and class rank are printed on transcripts. The grades are A (90-100), B (80-89), and C (70-79). There is no D, anything below a 70 is failing. Hope that helps
