Apparently its called 'B-school' for a reason

Thats what they told us in the first week. Dont care about grades. You're going to get Bs. Blah blah blah!

And after my first set of midterms I'm starting to believe it - the part about the Bs. Havent yet worked out how to stop caring about grades though! It is so hard to not care...especially having spent all of my high school and college life aiming for the top - to now be ok at being in the middle is scary. I know business school is not really about grades and it's about what you learn. But i still care damn it! I want to learn but I also want to do well.

The sad thing is I have no idea how. During engineering I know that if I put in a little more effort I could get that A or A+. What do I do here though? So many of the classes are so subjective, there is no way to know how I've done. I had a midterm that I though I had done decently - till I got the grade back!! And I know I put in all the effort I could. What to do what to do? Work harder? Pray even harder? Or start accepting the fact that it's 'B-school'??
