If I had to wager a guess, I would say 3.4 in 1987 is about equivalent to 3.58 today. An increase of .18 in average GPA’s over the last 23 years feels about right, although I have no way to back that up.
Either way I easily had that GPA, I think that chem grade was the only non-A I took in a science class. But I wasn’t much for being around blood or sick people, which pretty much rules out med school!
