I was asked by a teacher this morning how you can pull grades for the students in your team or house. Fortunately, someone has already set up those Ad Hoc reports for us! So here is a screencast to walk you through how to do it.
I had a teacher ask me if there was a way to hide or remove students who are no longer in your class. The answer is maybe. It depends on if they are officially dropped from your class and appearing as red in your roster and gradebook. If not, then no, you cannot remove them until they have been unenrolled from the class. If the student is showing up as red in your gradebook though, you can hide them so you don't have to worry about them. Here is a screenshot to help you do it:
