Thanks for replies. G&T workshop was a one day course for Maths at another Herts school, I will ask teacher for more information.
The school is a Specialist Technology College with emphasis on Maths, Science, D&T and ICT. Son has just had marks for mock SATs and got a 5b(1mark off 5a) in Maths and a 5b for science. Don't know about English. In view of your comments and specialist areas of school do you think it would be worth asking the school to send a letter confirming these results?
Yes definately obtain a letter on headed paper from school of predicted SATs results. If all 5s then that would be good.
