i just graduated. here's my rundown on the top and bottom of the professor heap. unfortunately you can't pick your 1L profs. that said...
the top: Professor Inniss, especially if she's teaching a bar topic course. I had her for property, and now that I'm studying for the bar I realize how well she prepared us. Sundahl is pretty new, but excellent when it comes to commercial and secured transactions -- incredibly smart, challenging and keeps class interesting. You'll work hard, but it is worth it. Mickey Davis is a genius, I had him for Torts and Copyright. The key with him is don't miss a class, and write down the rules exactly like he says them. He is by far the most entertaining prof you'll come across, and I feel so ready for torts on the bar because of his teaching methods. O'Neill is the nicest guy in the school, and a great prof. Only caveat is that he doesn't beat up on you in class, so self motivation is key.
Those were my favorites. I had others, all with strengths and weaknesses, but for the most part all were solid enough. Garlock and Ruben are both incredibly smart and challenging, but the workload is heavy. Ruben is really old school and can terrify you at times, but he really knows corporations.
The one to avoid at all costs: Professor Cherry. You could wind up with her for property, i had her for one semester. Terrible. Even if you get her for property DO NOT take her for Estates and Trusts. These are bar classes, and she teaches nothing.
Good luck at CM, I had a great time, it was hard, but I made it and came out with a great job. It may not be a Tier 1 school, but I feel like I got a top notch education. Now, back to bar studying...
