State Grammar vs Comprehensive and contextual offerWatch
So what is the point in being in a state Grammar School I wonder
apart from better personal statement, better working environment
Well, you just listed them. Being in a better working environment than a bad comprehensive ideally facilitates better grades which means you shouldn't need a contextual offer. Whereas someone who goes to a low performing comprehensive, who perhaps didn't have that environment, is unable to show their full ability.
I am in a state grammar can I mention that or will it be unnecessary ?
