Class of 95 alumnae here - Liberal Arts Major (specifically Letters, Arts and Sciences - make up your own major). Is that cool or what?
What everyone said above - it is a huge school, and is mostly upperclassmen - so as a newbie freshman, it can get a little overwhelming if you are not prepared for it. I wanted a big school, since I came from a small (@ 200 in my graduating class). Take advantage of all of the advising you can - and be in their face, since they are really not going to chase you down.
I was in a sorority, and basically joined up (actually a founding sister) because the rush was only a week long and the Greek system (IFC and Pan-Hellenic Councils) were changing the party policies. Shallow, I know, but I was a good girl in high school - I needed to let loose in college!
As for Greek Fraternities, not all are about the L & L (liquor and laid). Rushing for guys is really simple - you basically go around to all of the houses, and whichever ones you get a good vibe from you’ll probably get a bid, and you can accept it if you like, or not. And the houses are rally pretty varied - there are the preppies, the stoners, the hippies, the rich boys, the preppie stoners, etc. - you get the picture.
Bar scene - if you are underage - DO NOT EVEN THINK ABOUT GOING TO THE BARS. I mean it. Don’t try a fake ID, don’t use a duplicate ID - you WILL get busted. Same goes for apartment parties - they are almost always busted up by the cops. And DO NOT walk around with an open container. You WILL get a citation.
Freshmen are usually housed in East Halls for the first year - this is out on (what used to be) the very edge of campus, and across the vast Lot 80. This lot is very VERY icy in the winter. But, there is a Loop bus (it goes around the campus in a loop - get it?) that is pretty nominal ($.35 in my day) and is a good way to get to class. Many people bike, but bikes get stolen all the time, so you takes your chances.
The dorm food has really come a long way - there are many choices no matter what your dietary preference. One warning - stay away fromthe Creamery ice cream - it’s the ice cream in the dining halls, and is produced by PSU on campus. I’m not telling you this because it is bad - it is too good! It’s addicting!
Mmm - grilled stickies! Love the Diner!
Ah - winter. Snow usually starts falling about Halloween and it will probably fall consistenly until April or so. Get good hiking or construction boots with lug soles for traction - OPP did not do a good job of shoveling or clearing snow when I was there. Lotsa nice bruises from falling down.
History majors - one of my most favorite classes was by Prof. Spielvogel - what an amazing guy. I had his son for Speech Com 101 too.
Good times. Have fun, and don’t skip too many classes. You’ll regret it later!
