Grades graph

Is there any way to display grades of students by graph. Like showing a graph of how many students got more than 90% of a certain subject.

Hello! Take a look at Assess > Tracking > Graphing. It does not do exactly what you are asking for, but hopefully it proves useful. Otherwise you could write some custom queries for Query Builder, export to Excel and graph there. With a Value Added License you can get a stock of pre-built Query Builder queries that will set you off on the right foot. Cheers! Ross.
