I graduated with a Spanish and Psychology double major.  Psych was a challenging (but not impossible) major, and Spanish was decent- not great, but not bad.  The quality of any program really depends on which classes and professors you have.  Psych, Science, Econ, and English are the best majors.  Other programs- like Journalism and Computer Science- have small departments that I never heard great things about.

Study Abroad:

I went to Salamanca, Spain my junior year and it was a great program...but it was the ONLY program I could go on as a Spanish major to Spain.  Unless of course, I wanted most of my financial aid taken away and no guarantee of credit transfer!  That being said, if study abroad is important to you, know that OWU has strict policies and makes it very difficult if you don't choose from the limited program selection they have. 

People:

I am an open-minded person and made a lot of cool international friends at OWU.  There are a lot of East Coasters, Ohioans, and international students at OWU.  Sorry to say not many of these groups mixed, though I bet that would be the same at any school.  There are a lot of different clubs to join and a large Greek life, if thats your thing. 

Delaware: A small cute town with not much nightlife.  Columbus is 25 minutes away.  Find a friend with a car.  End of story.

Overall: I didn't like OWU the first two years, but after my study abroad experience I stuck it out and it ended up being an ok/good time overall.  The University has problems, but when I was there they made drastic improvements each year.  (Example: turning a boring computer lab into a 24-hour coffee shop, renovating one of the main dorm cafeterias, taking an empty frat house and turning it into a student lounge, etc.) I know they are currently renovating the gym, and the year before I got there they just finished a brand new science building.  OWU is like wine...it keeps getting better with age!
