When you get to your interview and they ask you about it, just be honest. You already got the interview, so they see your potential, they only ask about the low MCAT score because they are concerned how you might preform on the boards. They don't want you to waste thousands of dollars on Pod school and never pass your boards. If you did worst because English is not your first language, tell them that. If it is something else just explain it as truthfully as you can. But do not try to make it sound like it was not your fault, because it was in one way or another. My score was only slightly higher than yours and I explained to them that I had an extremely high credit load on top of working three jobs for the three preceding semesters and did not leave enough time to study for the MCAT (I started studying 5 days before I took it). They understood and I got in to all the schools I applied to with scholarships. So it is possible, just be honest and have a good reason for the discrepancy.
