Well done, really good results
I think the score went down to mid 140's last year and you can definitely put pates first on the caf, knowing that you will get your second choice should you not get in. It also means you effectively stay on their waiting list so if people drop out at any point it will go to the next one etc etc. I wonder how many 11+ tourists took the test? We heard someone from London was sitting at pates. Was that to intentionally move if they got in, or was it as a mock experience?
I would phone the school, they may give you a breakdown, although usually try to give as little info on the actual test as possible.
