Does anyone think this will change the overall complexion of my application? Will ADCOMs just trash my application if I can't make an A in quantum mechanics? Seriously no more threads like this. There is a quote by Richard Feynmann that more or less goes like "if you think you understand quantum mechanics than you probably really don't." People calm down. Diels-Alder, Kirkoff's Rule, Stoichiometry, Gaussian Distributions, PV=nRT, Mitosis, etc in the realm of things are not that important. If you can't make an A it is okay. I'd trust a doctor who is human and makes mistakes over some loser who made straight A's in college. We make mistakes for many reasons. Whether we learn from them or they humble us, mistakes are important. Calm down and take some Valium. Puke at a frat party, have a random hook-up, get arrested. In the long run you will sit back and laugh at these mistakes in your life and smile. Nobody sits in their rocking chair when they are in an "assisted living facility" and reminisces about a B in any class. If you don't believe this spend time in a retirement center or assisted living facility and talk to the geri's. They will all babble about stupid shiot they did in their formative years.
