<p>I'm wondering if theres any downside to avoiding certain professors and trying to get others using the service? I think I'm going to try and get an easier path and was wondering what other people thought. It looks like there are some huge disparities in difficulty of the same classes between the professors, like 18% A's in one vs. 61% for another. That's huge considering its supposed to be the same material... Obviously I won't be able to get every professor I request but I could use it as a guideline to steer.</p>
