Certainly at my school the "brainy kids" as a whole excelled across the board (apart from PE) I'd say the person with the highest intelligence (ended up doing maths at Cambridge) was by far the best artist in the entire school, one of the few people I have ever been jealous of - her pencil and pen and ink work was beyond exquisite . And all of us doing 3 sciences (long reason why that was unusual at my school) were all top in the creative studies we were taking.
I suppose I'm the exception that proves that rule
Then again, taking three sciences, two languages as well as the three mandatory 'O' levels (Maths, English Language and English Literature) and Religious Instruction (still mandatory back then) meant that there wasn't time for creative subjects (the way scheduling worked you simply had a choice between Geography and History) for those of us taking three sciences ([Physicist]If we're being very broadminded and are considering Chemistry and Biology to be sciences
