My kid’s high school has 80 IB kids per uear who apply through a magnet program application process. They are all very qualified if They make it all the way to the full diploma. They make up more than 10 percent of the graduating class. Of those 80 kids about 20 got in to LA or Berkeley. A kid ranked 50th in our class has a GPA around 4.5 and SATs of 1400 to 1450 or so based on the kid’s I know. They have a shot at Santa Barbara or San Diego but none in that range got in to higher ranked UCs that I know of.
