I wish I had advice for you @@ on your problem student. I don't though. I was one of those students that sat in the front row (hearing loss you know) and took notes, and tried my best and generally made A's. But I've been in classes where there were problem students, and as not fun as it is for the professor it is also not fun for the other students, because it is disruptive. I don't know about being seen with the campus security before class. It sounds like this student doesn't even have a clue and they might not even get the hint. But if you ever do feel threatened, I'd definitely do something. I hope you can get problem student resolved soon. My sister who is a preschool teacher has a problem parent this year (threatening a lawsuit because her child was put in time out). I texted back and forth with her this morning trying to help and calm her down. I sent her some Bible verses that seemed to help. I can't imagine what that child is going to grow up to be like. HUGS @@ which was the main point of my post. I wanted to send you some hugs.
