Is this a good mark for RCM Harmony 4 Exam?

I just got my results back too! ... I got a 92 (but probably failed my grade 8 practical), but my teacher kept on going on about how the average for Intermediate Harmony is about 66-68 which is apparently the lowest out of RCM's non practical exams. So 77 is way over average, and you still have a long time before postsecondary - music would be awesome to major in!
