Please consider adding a "Teacher Override" feature when grading assessments. With this a teacher should be able to click a note that is labeled as incorrect and deem it as correct. Then Smart Music can recalculate the score based on teacher input.
I would find it helpful to save the original assessment if possible. Much like google docs saves past changes to a document.
As of now I have calculated how many notes were in an assignment and created a spreadsheet so that I can simply count any notes that were in tune but given false negatives. I then have to put that into my spreadsheet to get a more accurate score. This is cumbersome, but the thing I can do to give the students the most accurate score.
