There’s a difference between top 10 in class which @maminami mentioned and top 10% of class.
I’m saying the actual top ten kids in my daughter’s class are not going to UCSD. Not even on their radar.
It’s a public school with an IB magnet program with 85 grads in a 700 kid graduating class, so not all the IB kids are in the top 10% of the overall class.
