Easiest Orgo 1 Professors?

<p>I had to drop Orgo 1 with Portmess this semester because I was failing. I need to take Orgo 1 and 2 for my major, but I am not very good at chemistry. The professors next semester are Sumerlin, Mcelwee-White, Miller, and Castellano. Who of those are the easiest to understand/don't make their exams impossible to pass (cough-Portmess)? I need to pass the class and actually learn some chemistry!</p>
