Also, I think its very important to remember that I doubt any admissions interview will include questions like "tell me why you scored low on the quant section, do you struggle with colored ball probability questions?".
Its just my view, but I think programs should just say "get a 300 or whatever, done, we anything above that is irrelevant". Sorta pass/fail.
These entrances exams are utter nonsense in my opinion. What do behavioral MCAT questions have to do with anything, or GRE writing sections? At best they are loosely connected to program content, at worst they are an unimaginative tool to filter out applicant pools that are too large. Easier to hit the filter button on excel with GRE scores than read someone's personal statement.
