“That’s interesting. Just taking a look from the published Oxford results from this cycle’s MAT, 90%+ of the MAT takers scoring in the top 10% got an interview. I wonder if most of the <10% who didn’t get an interview are international.”
Those who don’t get an interview likely have relatively poor references. It wouldn’t be surprising if more international students don’t have such good references because their referees have less experience in writing one.
