Lizzy, I know you've seen me suck up to you long enough to realize I greatly value your opinion on everything related to admission.. but I do hope you can reconsider your stance on graduate school grades, even just slightly.
During my graduate program I took some of the same undergraduate courses that the other pre-meds took (molecular genetics, immunology, histology) with 60-100 other pre-meds, almost all of which were typical junior/senior undergraduates. we had the same book, same teacher, took the same exams, and were graded on the same scale.. sometimes the graduate students also had to do additional papers/presentations. I earned the same A that any other pre-med would have earned.
graduate grades are usually very good because graduate school often selects for intelligent, hard-working individuals in the first place. they don't just give us A's.. I had to work very hard for the A's that I got in graduate school. my knowledge in the subject can demonstrate that to you.
anyway, I just hope you can read this and maybe the next time you see a 4.0 in graduate school you won't just think "Yeah, typical grade inflation...". Maybe you'll consider that we did work very hard to earn those grades.
