Or class rank - but I suppose they can just look up the stated latin honors policy.
On the other hand, grad schools might also look specifically at “subject” GPAs - how the student did in those courses that are relevant to the graduate studies. And, of course, they’ll have input from the evaluations/recommendations that professors and internship positions wrote, to “round off” the picture.
Remember, most “grad schools” are also universities with undergraduate colleges. They know very well how “the system works” - and how to “sift” through the smoke.
