Sutton Grammar School SM1

[jmb72]

Hi There,
After some inside info re. Sutton Grammar. Putting my son in for SET test etc (currently Yr 5) able and stands a good chance apparently. Possibly unlike some parents I'm seeking a school which pushes but also massively nurtures and concerned that SGS might be a little too uber competitive. I'ld love to find out what the actual atmosphere is like in the school once you're in. I know it has a great rep for pastoral and certainly less hot housey than the other Grammars but to what extent?
How much homework would a typical Year 7 boy receive per night?
Is there a supportive or competitive atmosphere? Or good balance?
Is it heavy on the STEM subjects to the detriment of others?
Are the boys happy?
Any insights welcome. Thanks so tricky when all the open days are virtual ATM!
