The percentages I’m quoting are from what is self reported by U MD on the common data set where there is no mention of weighted vs unweighted. We do know that each college recalculates gpa from a student’s high school transcript to fit their own priorities, so we rally have no way of knowing exactly how to interpret gpa information.
This OP self reports that her son/daughter is ranked in the top 5-10% of her/his class, that is positive mitigating factor since U MD reports that only 66% of this year’s freshman class were in the top 10% of their high school’s graduating class. I’d rather be conservative and say toss up rather than promise likely and mislead.
