From one bad MCAT taker to the next (I got a 22), this is what I said when asked the question:
"Yes it was low, I had a heavy load that semester, was planning my study abroad and could not afford the class. However, that being said, I would like to say that I believe that I am MORE than my numbers predict. Yes, the MCAT may measure how I will perform on the boards and my high GPA shows what I did for four years. None of my scores, however, can ever predict compassion or empathy. I may not be able to retake my MCATs now, but, I can assure you that I WILL be the type of physician that puts my hand on the patients shoulder and treats them as not a patient, but, rather, a person. I would ask that you look beyond my scores and at me, here. This interview is WHO I am and WHO I will be."
I was asked that low MCAT question at two interviews and, so far, I have three acceptances, the biggest being to my top school (DMU). Just remember, your scores or only as low as you sell them. You an interview, now show them why those numbers aren't worth the paper they are written on! 👍
