<p>IMO commondata is the most accurate way to gauge a student’s chance of being admitted to a school. I studied the commondata for the schools my son applied to very carefully, including boy/girl ratio and OOS admits. So far we have been correct in our predictions for the seven schools he has heard from (6 admit, one deny). Yield and ratio mean nothing because you don’t know what you’re competing with, whereas commondata gives you specific numbers to compare your personal stats to.</p>
