It's a great school, it's ranked as the most Religious and Conservative public school in the nation and there are several Christian groups with membership upwards of 300 students.
They're also 2nd in the country for job recruitment preference by major industries, and they offer a fantastic honors program. Plus with your PSAT i'd assume your national merit, and they offer full tuition scholarships for that (both in state and out of state). Even if you arent national merit, you will still likely be given an out of state tuition waiver and a McFadden scholarship, which would reduce COA to roughly $8500 a year.
The greek/party scene is also easily avoidable. greeks only account for like 5-10% of the student body. They're academics are also really respected!
Seriously though, check out Texas A&M. I'm a Christian too and I'm probably going there because of the awesome environment!
