As I mentioned previously, most classes are quite large. In my experience classes as small as 10 to 15 people are either highly specialized classes (that generally you won't have until junior or senior year, or maybe not even until grad school), or classes that are bordering on being canceled or just unpopular. Professors do seem to make an effort to know your name, especially if you come to their office hours (and I've never had a professor who wasn't happen about their students caring enough to come to their office hours, even if it was only once a semester), but many classes will invariably leave you feeling distant from the instructor.
I think it's fair to say that the professors in general try harder and care more than the strong majority of their students in most situations. I've found, especially after the advent of Facebook, that there are more students asking others for notes, tips, and cheat sheets through the internet than ever actually ask the teacher for help or approach the teacher at all. I'll be honest: The only time I WASN'T disappointed with students at PSU, for one reason or another, was when I was in a "high dropout" major where students had to be highly dedicated and almost obsessive just to get in. These student were on par with what I had always considered to be advanced level high school students in AP classes. Anyway, if I haven't made it clear enough, coming from my high school in State College, PSU was an academic let down.
Unfortunately, there are fairly significant differences between the qualities of students, classes, and professors at PSU by department and major. That being said, I'll just be more specific about my own majors and my experiences there:
I was a Music Education major for my first 3 years. The faculty of the music program are excellent, and the students very, very dedicated. The program is exceptionally difficult - I believe when I was in it it had about a {4a082faed443b016e84c6ea63012b481c58f64867aa2dc62fff66e22ad7dff6c}60 or so drop out rate. If you're pursuing this degree, I strongly recommend talking to a few music majors about it first, there are a lot of details that make it so tricky. Probably biggest weakness of the music department, other than tending to overload its students, is that counselors tend to be weak and not really capable of helping you much more than you can help yourself (unless your counselor is your personal instrumental/vocal instrucor, in which case they tend to be excellent). Music Education however, whose curriculum is, I think, still be revamped a little bit, has its own blips. I can't help but feel that they don't give their students enough of an idea of what life is like as a music teacher in public schools before the core of classes in junior year hits. This is why I dropped out so late - I was so dedicated (necessarily so just to survive the first 2 years of the major), that I didn't realize that I didn't want that kind of life and I didn't want to be that kind of person.
And, it's rude and maybe it will come off as childish, but there is an instructor, Dr. Rukowski, who also seems to intentially single out students to fail out of her mandatory junior-year class just to make her look good. It's pretty well known, and if you talk to students that level or higher they'll know about it. I've seen and heard of her doing it to many a deserving, intelligent, hard-working student, but because she has so much tenure in the program, any student who fights her decision will lose. And the way many of these students are dismissed is ridiculous, unprofessional, and disrespectful, and I was one of them.
Anyway, I then changed to an Integrative Arts major with a minor in Information Sciences and Technologies. Integrative Arts is a fairly loose major with at least one very excellent counselor who will make time for you and give you excellent advice, but the major is what you make of it. However, what the counselor in the Integrative Arts tell you about the major (especially Bill Kelley) before you transfer into it is very very accurate, so I don't feel any need to say any more. My experiences in that major were very good, although my classes for my IST minor were very frustrating. Professors were good, but I feel that the curriculum needs to be revamped significantly, as generally students either find it very confusing, or information that they already know. And, unfortunately, I learned too late that working in groups with "normal" PSU students is a bad idea (laziness + "I need my 'A'" = scape goats and last minute crapwork), and all IST classes place a significant part of your grade in just that.
