Good MCAT scores are an absolute requirement to become a good doctor!
Just the other day I went to the emergency department because of a sports injury. I asked the doctor, "If I throw a rock at an angle of 30 degrees and an initial velocity of 250 mph on a 200 foot tall hill, how long will the rock take to hit the ground?". The doctor took more than 2 minutes to answer, and his answer was wrong! I'll never see that doctor again. What a quack.
Almost reminds me of another quack I saw the other day in one of my clinical rotations. He really knew how to talk to patients, and his knowledge of diseases and therapies was top notch, but he couldn't figure out the products of a Claisen ester condensation! Geez. How do people like that become doctors in the first place?!?
