Don’t dwell on CC horror stories. There are amazing high stats kids who don’t get into their favorite colleges but if they are smart applicants, they’ll still have plenty of great options.
Your son has great stats and is a contender anywhere he chooses to apply. Cast a wide net. Yes, the UC’s can be a bit of a wild card but apply to a sampling and he’s sure to have some choices. There are lots of great private school options too when money is not an issue. It’ll work out certainly!
