DD2 has just had her IB results. Out of a cohort of about 33, 7 got more than 38 points, including 2 who got 44 out of a potential 45. Only 1 failed the diploma (average failure rate globally is about 22%).
The college is imo a really good place- it seems to working really well across the ability range with something for everyone. In 2008 it was given notice to improve. In 2012 it had one of the govt's pilot no-notice inspections and received "outstanding". It certainly DID improve!
