I had the same situation when applying for schools in my home country and here in the US. I made my decision upon what major I wanted and what requirements they asked for. Also, I focused on the college or the department I was applying to by reading the introduction that is written by the head of the department.
After reading about mission statement last week, I tried to look at different universities I am applying to for a job. I started to notice the differences between public and private universities.
i find the statements really interesting to read as they tell us so much about many things in a short paragraph.
