I read what the Rutgers site said, and as far as I can tell it still ought to qualify as rolling admissions. That’s certainly the position I would take with Penn, if the issue came up (which I would try to avoid, if possible). Rutgers says that it will review all applications as soon as they are complete and notify students as soon as a final decision has been made . . . usually four to six weeks after all elements of the application are complete." Early Action applicants are guaranteed an answer by January 30, but can be admitted long before that, as can RD applicants.
It’s hard for me to believe that Penn has lost a meaningful number of ED acceptees to Chicago, MIT, Caltech, or any other university at which this ciould possibly be aimed.
