<p>The curve does depend on the class. The worst curves for me have been in the really large classes.</p>
<p>The only issue you might have with class availability is getting into a popular General Education class as a freshman. Freshman register last, so when they are trying to register for a class that seniors, juniors, and sophomores are taking, they don’t always get it.</p>
<p>Professor availability depends on the professor. You will probably interact more with your TA, which is better anyway since they will be the ones grading you. TAs have a certain number of office hours a week where you can go in and ask questions. They also give you the option to make an appointment with them if you can’t make their office hours.</p>
