Class registration for next semester recently having gone by, it's probably a good idea for me to talk about it. When I came for Orientation last summer (wow--almost a year ago already!), Orientation was one of, if not the last, part of the event. Everyone was nervous because, let's be honest, none of us knew a thing about what classes to pick. We were all already pre-registered for freshman Civ, and those of us with majors were all pre-registered in the "101" class of our field. Since freshman take only four classes a semester (more, with permission), that left just two choices to be made. I know that doesn't seem like a lot, but somehow it appears to be momentous at the time.
The orientation leaders gave a nice class on how to use PC's online registration and management system, Cyberfriar. They showed us how to navigate the books that list the available classes and other such materials.
Still, I was nervous (and I wasn't the only one) because as incoming freshmen, you're the last to register. Mostly, though, the upperclassmen have already taken, in their academic career, most of the classes new freshman want/need so there's always space available somewhere.
Of course, things worked out fine for me (like they will for you)!

Also, if you hit a snag and there's a class you must have that's all full, just politely talk to your academic adviser or the secretary of the department running the class. That's what happened to me this semester, with my theatre classes (since I just recently declared it as another major). I got a lot of great advice and help, though, and by the end of the registration day I was enrolled in both the classes I need. I'm very, very excited about both of them!

Also, for those in the class of 2012 who have decided on PC (!), don't forget to go on Angel and take your math and language placement tests! If it's the same as last year (I'm not sure), the language one isn't mandatory, but you never know when you might need to take a language class so it's always beneficial to know what level you need to be in!
Also, if it's the same as last year, you'll get the results of your placement tests at Orientation!

Best of luck to everyone!
