Yes, I think I gave you that potential misunderstanding Only A's and B's "pass" but the people you are in graduate school with are all like you so are very smart and work hard and got A's and B's in undergrad classes so the classes are of a difficulty so it is expected everyone will get A's and B's. Is that clearer? It can be harder to get that A (since the difference between success and failure is smaller) but when I got an A, since I was "Me" I took it more for granted than lizardlady took hers. But then, I know "I'm never lost because I am with Me" (how can "I" be lost with "Me" there all the time? :-)
