It's patronizing, but I wouldn't consider it crossing the line to bullying or abusive. I read it as someone who considers themself to be in a position of experience and authority counseling a newcomer on the rules of the road. Perhaps the "inner voice" that reads that text to me on the page differs from the student's inner voice?

It's hard to discern tone from text on a screen, and easy to attribute meaning to actions that did not carry that intent.
