<p>Step 1 - stop watching youtube videos of stupid college students. You can’t judge any college based on those. Or if you did, you would need to stay at home and commute to a community college.
I understand what you are trying to find and this question comes up a lot. (try searching here on “drinking” or “partying” or “greek” and you will see other discussions). There isn’t any good way of avoiding immature college kids, they exist everywhere, more or less. Trying to find campuses where there are fewer idiots is tricky. My son tried to factor that into his college choices too 
Try looking for lower % of Greek participation, LOTS of student clubs/activities relative to the number of total students, perhaps focus more on schools in urban areas - but none of these are sure-fire ways of avoiding the problem.</p>
