<p>All of this depends on the professor. Some arrive early, some late, and some on time. Some professors ask you to call them by their first name while others insist on begin called Dr. or Prof.</p>
<p>Just show respect and fix any mistakes you make and you’ll be fine</p>
<p>I’ve always addressed them as Professor ____ unless they tell me otherwise. I would never go by Mr/Ms. I hear that some female professors may be sensitive to this, since they already don’t get as much respect as their male peers, esp in male-dominated fields. Haha, aa6590, I can just imagine the annoyance that went with “Ms _<strong><em>”. Lol, “Mrs/Miss </em></strong>” is even worse.</p>
