I went to BYU and although I will be the first to admit that it is not for everyone, it was for me. I just graduated about three years ago and so College is still kinda fresh to me. When I decided to go to BYU there were a lot of factors that lead me to that conclusion. A couple factors were-- Of course education. I did get into other very good Colleges, but decided that for my major BYU was the best. Another was Location. I wanted to stay on the West and had no desire to go anywhere East of the Misssissippi. I grew up in Hawaii so I didn't want to get too far from home. Another was Family. At the time both my older brothers were at BYU and I really missed them-- so I wanted to more then anything go and just hang out with my brothers and just be around them. For awhile I could not make up my mind between USC, UCLA, and BYU. I grew up with quite a few members of the church and I really wanted to continue that. I didn't want to have to worry about other distractions of the world and just wanted to focus on school. Although I did consider other Colleges, I grew up in a very huge BYU family and due to my major it was kind of a no brainer. Now, had I had a different major I am almost positive my school of choice would have been different. I loved BYU, but I was not going to let my love of BYU decide the quality of education I received. For my major, I feel BYU offered the best quality of education.
I've had people ask me if I went there to get married. I think that if you are going to college to get married--stay home and go to a singles ward. I think if you go to College and get married great, if not don't worry about it. Granted, I met my husband there, but he and I were best friends for a couple years and did not even talk about dating until we had about 2 months left of school. I was never "The married student"--thank goodness and never went there to get married.
I think you really need to consider what you plan to major in and do your homework about that specific major. Talk with professors, if possible talk to students who are currently in that major, and definitely tour the campus and feel out the school if possible. Ask other students how their experience has been at that one specific school.
When it all boils down I think you of course need to do your homework on the Unviersity and make a list of what you want out of your College education/experience. Decide what is important to you about a College and what isn't and then go from there. Go where you feel is right for you and not for your friends or your parents.
I hope this helps!!
