@waitinganxiously984 This is true for GCSE, however in 2019, for example, Tormead's A-level results were better than StCats, especially at the high end. A32% compared to StCats 29%. A-A Tormead 67% to StCats 64%, A*-B pretty much level on 87/88%. Each year different cohorts do better than others, the tables always show these undulations. If you average them out, you are however right that StCats edges slightly ahead on GCSE results.
Uni destination wise, the 'volume' of leavers going to top universities is higher at StCats, however Tormead's sixth form is 1/2 the size, so proportionally, they can be comparable. It's also about choice, in 2019 the Tormead exam results were better at A-Level, but no one went to Oxford (one assumes they could've, as most years multiple students do), however a lot of the cohort seemed to choose medicine and sciences elsewhere. St Cats, with lesser A-levels sent a few to Oxford that same year. Finally cohort size has a massive impact, Tormead has smaller year groups, especially at A-Level, therefore it only takes one girl to drop the ball and have a unfortunate exam day to completely lower all the results... when you have a bigger group, 'unfortunate days' can be averaged out/absorbed.
...As you can see 'the tables' are all good fun, aren't they?!
With these two schools, academic wise, we're comparing apples and pears really. What I always thought it was about was simply where you want to go for every other reason, because whichever school you choose, as long as you work hard, they'll get you to where you want to go.
PS. apologies in advance, im a forensic statistician by trade and went through all this when picking for my daughter..... it didn't really help, but made me feel good! haha
