Transferring to St. Olaf

Hello, I am currently a freshman at a prestigious university. I am considering transferring to St. Olaf next semester (spring). Are there many transfer spots available for freshmen?
Also, what is St. Olaf really like? We you recommend it to others? I am unhappy with my current schools because it is nothing like it seemed to be when I toured and read all of the pamphlets. Is the religious aspect of the school pretty dominant? I am Lutheran, and of Norwegian descent, so I think that the heritage and religion is a very important part of the school. I am pre-dental and will probably major in biology. Are there any programs for pre-dental students?
Thank you!
