<p>Email professor asking for some time to sit down with him to explain why you got a B. Give him a 2-4 weeks to respond. If he doesn’t respond, email the department head. Remember, this is about why you got a B, you need to make sure you find out. Find out where you messed up, fix it, and move on. You pay your professor’s salary, not the other way around. If nobody will respond to you, there should be a procedure in place to appeal your grade. Let your professor/department explain to the committee why they didn’t have time to respond to your email. Again, you are paying for this class, you have the right to know why you got a B.</p>
<p>One last thing, which is a bit of a tough pill to swallow. Don’t do anything that your academic career can’t handle. I’ve kept my mouth shut once or twice in an effort to not burn bridges I might need to cross eventually. Check the syllabus, check the catalog and know exactly what the procedures are.</p>
