After being told at the schools meeting that there were enough GS places for all the IC boys who passed, I emailed SHSB asking for confirmation and just got the following -
"You have correctly summarised what Dr Bevan said. The crucial part is that you should put BOTH grammar schools in your choices - so in your case SHSB first and WHSB second - so that if you do not get your first choice, you will definitely get your second.
Hope this helps.
In other words, if your DS is in catchment for the Southend GSs, if you put them as 1st and 2nd choices, your DS will definitely get a place at SHSB or WHSB if he got 303+ !!!!!
