For us there are four big lessons learned from 11+ Birmingham September 15
1) Speed is used ruthlessly in this exam
2) Any one with fast reading ability and a wide vocabulary (has a huge advantage, due to the 50% weighting) - DD scored much stronger on Walsall CEM 11+ due to strong maths, less speed pressure and equal weighting.
3) You can still succeed in many comprehensives (so relax, took me a while).
4) To use an old English saying, you can take a horse to water, but you cannot make it drink.
I have two kids. One has to be cajoled, the other doesn't. That is likely to be a far bigger factor in success, than the environment, school or tests taken. If I could bottle motivation!!!!!
