<p>Ok - We generally do not have a waitlist system. It works like this</p>
<p>Normal - Seniors with the highest number of credit hours get to register first. It proceeds down the ladder to juniors, the sophomores. There are spots reserved for freshmen</p>
<p>For some very popular classes - The registration is uncapped. Then the professor does a lottery or picks people to fill capacity</p>
<p>If you just cannot get in - You can check the online catalogue and wait. What I prefer doing is going on the first day of class with a special registration form. If the professor is willing to add some people, they will sign it for you. If not, I usually ask them to let me know if someone drops the class. In the meanwhile you can go the the class (if they let you). Usually people drop the class within the first few weeks.Also registration occurs the semester before and there is winter/summer in between where some people finalize their schedules and spaces open up.</p>
<p>Generally speaking, seniors are given preference. If you are in your last year/semester, the professor will be much more likely to allow an extra student.</p>
<p>The ultimate “dirty trick” is to have a senior register for you. Then at some odd hour of the morning, (when no one else would be registering) the senior drops the class and you add it immediately. Never tried this one personally (got in by asking nicely) but I have heard about it.</p>
<p>Does this answer your question? Once again, apologies for the misunderstanding.</p>
