Suggestions for Talking to profs

<p>I'm going to meet with a prof on Friday to discuss about possible research projects and would love to have advice on how I should conduct myself such that I could make a good impression. For example, if I should be formal or not. Thanks!</p>

<p>Also, the professor put directions to his home address on his homepage. So this could be taken as a positive sign in that he's willing to reach out, eh?</p>
