Hi I am a local tutor and many of the children I teach want to apply to Rainham Mark, it is a co-ed with more boys than girls attending. It has a good reputation locally and in the last couple of years has set a cut off mark about 5 marks above the Medway test pass mark. In my opinion it offers a good education and has good pastural care. I have heard that the amount of homework tends to go in waves of not enough or too much but I think this can be said of any school.
The feedback I get from parents whose children have been there for a number of years is that they are happy and educated to a high standard.
I'm not sure what age your child is and whether they already attend a grammar school, depending on that you may have to sit an 'entrance' test; also as it is so popular there may not be spaces in the year group you need so you may have to go on the waiting list.
PM me if you want any more details.
Thanks for your reply reddebs.
