With the high school and middle schools working on posting grades lately, there have been a flurry of requests for help. For those of you who have been using gradebook (beta), like I've been suggesting, you'll notice that past guides on how to post grades don't match up to what you see. So I went through and created a new guide on how to post grades and comments and did a screencast to walk you through it for those of you who do better not following written directions. Both can be seen below and are posted in under the "Resources & How To Guides" tab above for future reference.
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:
