It's hard to see how the algo could do anything but disappoint. If you don't have the exam information, what information have you got left? Just results from previous years, and a guess as to where you might be in the class, from a teacher who doesn't want to disappoint anyone.

But people have since forever seen exams as a way to stand out from the crowd, individually. If you went to a bad school, exams were a chance to show some extra effort. If you were a slacker, you'd be found out.

Without the specific exam results, all you've got is the reputation of the school, and chances are variation within a school is greater than between.
