You could never get into H,Y, or S
First of all, she did. You are the one who doesn't know how the law school admissions systems works and you don't want to believe the truth. She knows how the system works and what it takes to get into those schools.
The first thing that is wrong is that you picked stats for the toughest admissions season in the last several decades.
She picked the most recent year, which is not wrong. Because the economy is still recovering, this admissions cycle will be very similar.
The second thing that is wrong is that you are severely undervaluing OP's three stellar years and one bad year.
You are overestimating the effect of three good years. Yes, it's better that the OP has three good years to show instead of 4 mediocre years, but in the end it's just a 3.5 that will be submitted to US News and that's
what matters to law school admissions, not grade trends.
