I just wanted to add another dimension to the discussions. If you didnt already know your son/daughters standardised score (as in previous years) you would put your choices in order of preference. The fact that you know them in advance is to a certain extent helpful but also seems to be clouding everyones decisions to apply for certain schools. If you have 6 choices then realistically what have you got to loose in putting your 1st and second preferences on there even if you a little of the mark ? ........just a thought.
I agree wholeheartedly. There may be some people who will no longer be considering grammars and can now ensure they put the best (for them) comps on the CAF, and there will be those who were not considering super-selectives, but now might. Outside of that I'm not sure the info provided is a great help, so real order of preference is the only way. You won't be penalised for putting a school 2nd if you don't get first choice.
