I think that if class rank is suggested by major and overall school, it would be helpful but unlike high school, there may be students that take easy majors and get 4.0s. Afterall, we do not take classes all the same like our peers. On the whole, we don't get extra points for pursuing hard classes either like in high school where AP was offered and an unweight gpa was included to provide perspective.
I would like to ask the dean of my college to write a recommendation though to put into perspective how hard my major was but I'd rather they not standardize me by numerics.
