I believe that all reviews contain a certain bias. If students have positive experiences then they render favorable reviews. On the other hand, students reflect their negative experiences in their reviews. It is important to remember that the truth often lies somewhere in the middle. There is no one 'right' school for any student, and your college experience is what YOU make of it!
Having stated that I have only positive things to say about Penn State. I believe that I received an excellent education, and as a Schreyer Honors College scholar, I had many learning opportunities both inside and outside the classroom. I know that PSU has a party school rep, although I think that the same reputation could be hung on almost any school, with the exception of some small Christian colleges and BYU! If you want to party, then come to Penn State. However, if you want to work hard and learn in a world class educational environment, then come to Penn State! I had to maintain a higher GPA at PSU to remain in the SHC than any of my friends in their honors programs at other universities. I also had a graduation thesis requirement to satisfy. All those reviewers who comment on the poor work ethic of Penn State students might be reflecting on their own lack of effort, and perhaps that is why they were unsuccessful. Also, it amazes me that some students complain about the lack of diversity. What do they expect to find in a small college town in the middle of Pennsylvania? Seriously, if you want tons of diversity then choose a inner city college or university. Penn State attracts students from all over the world, but the majority of students come from the mid-Atlantic area, so the student body is only slightly diverse. However, there are clubs and organizations for many different groups of students. As with any school you will need to get involved, join organizations with like-minded people and you will find your peer group.
I had some really good professors and some not so good ones, but, again, I think this would be the same at any university. Penn State is a big school environment so choose to go elsewhere if you are not a self-starter, and still need some high school type hand-holding. Freshman year lecture classes seat hundreds of students, but if you sit in the front row then who cares how many others are in the same room seated behind you? I made some good friends, did some partying, went to some exciting sporting events (not just football), graduated in four years, landed a good job in my career field, and have some wonderful college memories. That's what it's all about! I would definitely choose Penn State all over again.
