<p>It’s true that the grading system is not narrative now, however, the option of CPRs and SNC grades were far, far more popular in 1979 then now. For instance, the year after the inception of the curriculum, ~80% of classes were taken SNC and many of those people had CPRs alongside the SNC grade. That would be a “narrative grading system”, however, the number of courses being taken SNC at Brown and CPRs being requested has significantly diminished. Now only 20% or so of courses are taken SNC and CPRs are rarely requested.</p>
