<p>This can be either awesome or terrible.</p>
<p>Before you register, be sure to go to ratemyprofessors or ask people how this particular professor is. If he is a good professor then go for it! You will get to know your professor more than the other students, and that can help you a LOT in the long run. I have had the same professor for all of the chemistry courses I have ever taken and I absolutely love it; I understand his teaching style and it makes the transition into a new class so much easier. And like stradmom said, you never know when you might need someone to put in a good word, for a professional reference, or a letter of reccomendation! Good luck!</p>
