True, but as you get further towards "A" average, the seeming difference between an A and a B gets more important.
The only person I have ever known to have cried over grades was someone who cried over getting a B+ instead of an A. I know many more people who got D's instead of C's -- they didn't care.
I cared when I got a D instead of a C in my statistics course, but only because I retook it to get the D off my transcript. What really stung was I got the basically the same grade the second time around, but the professor (same professor) did a curve that year. I replaced that D with an A. Where was that curve the first time around?
Yeah, MIT versus SUNY essentially. I got A-Bish grade average but did well enough on the SAT to get a scholarship to a SUNY and said F it to the prestigious schools. Happily in less debt now. Didn't make a difference (well, retrospectively, perhaps in a different timeline, I'm a well-respected researcher with a PHD.)
