Our school has a 4 tiered system (H, HP, P, F) like many others, but they absolutely do rank us, although they refuse to admit to this fact. If you ask them, they won't answer the question directly. However, our academic adviser gets our grade report which has a class rank for each exam and overall printed right there on it. Unfortunately, they are not allowed to let us see this report and supposedly get in big-ass trouble if we are caught viewing a copy. I don't know definitively if this rank goes on the Dean's letter, but I can't imagine any other reason we would be ranked. Overall we are treated like little children who can't handle the truth.
So every school does it differently, but just because your school says one thing doesn't mean they aren't doing something completely different behind closed doors. Glad I'm paying 38 grand a year for this kind of transparency and student focused education.👎
