The standardised score goes up to 170 but I've never heard (personally) of people with scores higher than about 145 - so well done to your DD.
For anyone feeling even more shit in the news of other people's successes, I know you know this, but it's a snapshot of how well they did on one test on one day. The system is brutal and doesn't measure how well they draw, or how good they are at football, or how resilient they are, how well they pick up languages, how amazingly they can sing or play the cello or how reliable and kind they are. Kids with parents who care about their schooling (that's you!) generally do just fine in the end.
