Min 303 should get a place. I believe SHSB is the only Southend grammar school in the past to be over subscribed with local applicants with scores 303 and above. So as ToadMum described that's what happened there. That is unusual though and even with the boundary changes 303 should get a place at one of your chosen Southend grammar schools. They usually don't get enough local appicants with 303 and above and they expect the same this year.
Typically, DS wants to go to SHSB! I wonder why that one was so popular?
So, it sounds like there won't be a pass/fail on the day, then-but will indeed be a mark and then the higher over 303, the greater the chance you have of securing a place. If you have under 303-there will be NO point in putting down any grammars on your list of 5-yes?
I just want to know now!
