<p>I had the very same questions last year. Sometimes, I miss being a freshman. Do make the best of the year 'cause honestly, it is a blast!</p>
<p>Preregistration - most classes at Yale are open to anyone who wants to take them. Obviously these are all lectures. Seminars, on the other hand, by their very nature, cannot be open to everyone. So they select the students by doing “pre-registration” which is basically registering for the class before you officially register for classes at the end of Shopping Period.</p>
<p>Different departments handle it differently. For math, for example, you have to take the placement exam and then go stand in line at the preregistration meeting on the first day of classes to put your name on the list. This is first-come, first serve. For most other departments, they do it electronically, where you just select your preferences from a list. This is the case for English and freshmen seminars. They are based on a random lottery and there isn’t much you can really do to tilt things in your favor. </p>
<p>Departmental seminars (like history seminars, junior seminars, etc.) are usually only open to students in those majors and in certain years. The chances of freshmen getting in are almost impossible - but can be worth a shot.</p>
<p>“Permission of instructor required” just means that the class is a seminar and that you need to preregister in some way. For some, like English, freshman seminars, and Math, I already explained the process. For the dep’t seminars, I’m not too sure what the process is since they’re mostly major-specific. But there’s some sort of “signing up” process you do at the end of the year or over the summer (hence, why freshman are usually not allowed to take these). You don’t need “literal” permission. A lot of times, if you show up to the first day of class, the professor will pass around a sheet for you to sign and that’s how you get permission. All depends on the class.</p>
<p>You don’t need “permission” to shop. Even if you don’t get placed into a freshman seminar, English seminar, etc. you can show up to the class and then tell the professor that you’re interested in taking the class and you’d like to be placed on the waiting list. If anyone drops the class or if the prof opens the class up to more people, then you’ll be contacted.</p>
<p>For freshmen, most relevant preregistrations take place during Camp Yale and you’ll receive e-mails about that in about 2 weeks (OMG IT’S SOOO SOON!). Btw, this includes Econ.</p>
