Being senior can be a proxy for performance (to some degree since colleges don’t keep students who get failing grades). FWIW, at my colleges that I went to, people on honor roll were given a few hours head start on class selection.
That's not an applicable proxy. Sure they might have low performers dropout, but they doesn't provide any segregation in the remaining cohort for high performers getting to register early.
I disagree that is “not applicable” but as I said, just a hunch/hypothesis. It def requires experimenting and research to prove whether it is or isn’t a proxy, at least for this case.
