Hi, I am in a similar position, aiming for my son to sit exams next year, but am clearly well behind you in terms of preparation. Only just starting to think about tutoring, school options available etc. If you know which schools you will apply to (is that easy in your area?) I read that it is useful to target the preparation on that basis, and try not to overdo it too (i.e. let your boy to have some fun during the holidays too!). BR
We're aiming for Ilford County High but with the whole of Redbridge boys trying to get one of the few places it'll be tough. This year I heard almost 1,000 boys took the exam and only 180 will get a place.
We might try some of the scholarship exams as well for Bankroft and Chigwell School but that very much depends on how he's progressing particularly in English which is his weaker area. The free writing part of these tests isn't something which he enjoys.
Yes, school holidays and fun is a tricky thing during the final year of 11+ preparation. There were almost 250 children attending my son's holiday course which shows how many people are "chasing the dream..."
