First, the student. One student may know the material like the back of his hand and end up helping prep his classmates for exams, but come exam time, get stressed and do worse than he should. Of course there could be others who perform above their expectation, but I find that to be less common in my own experiences.
What about the professors? I think at this point in our academic histories we have all seen the professors who come up with ridiculously complex or ambiguous test structures or questions that don't test knowledge, but test students' test-taking abilities.
Put these two factors together and you get some situations where the smartest may not rank at the top of the class, and some less knowledgeable students break through to the top. I don't think anyone should resent this - after all, it's like comparing college football's BCS rankings (for grades, the "perfect world"...hah I just called the BCS "perfect") to any other sport's playoff system (for grades, the real world). Ultimately students have to perform against the evaluation structure that is set up for them. But I do think it's a choice every MBA student has to make coming into their programs - am I going to focus more on the grades or the content?
During my time at Michigan, the students with the best experience, personality in the interview, and communication skills generally landed almost all the most prestigious and desired internships and full-time offers. These attributes don't always correlate with GPA (some people who got those jobs didn't even put their GPAs on their resumes). Their results were a big part of my decision to focus on other aspects of the MBA program beyond grades.
Fortunately, schools attempt to mitigate individual focus on grades and encourage collaboration through three different policies that I'm guessing all MBA programs use at least one of:
- Grade Non-Disclosure: Everyone receives a GPA, but during recruiting, students are not allowed to disclose their GPA to on-campus employers.
- Changing the Grade Scale: Ditching the traditional A/B/C/D/F system and reverting to elementary school-like grading of "high pass," "pass," and "low pass" (or some other similar variation). Another variation is to use letter grades but eliminate +s and -s.
- Modifying the Grading Curve/"Grade Inflation": Stick with As, Bs, Cs, etc. but adjust how many students receive each, usually allowing the bell curve to peak around a B+ and have very few get less than a B-.
Ideally I think all schools should adopt #1 in conjunction with #2 or #3, as #1 has no effect on anything other than not allowing students to disclose grades during on-campus recruiting. If Stanford can do it, I think others can too. But implementing at least one of the three is very important in the overall MBA learning experience.
