Cheam - when do you have to register to get a good chance of a place?

DD was 11.5 months when we registered her (April baby) and the letter is not clear as to whether that is likely to be a guaranteed place or the waiting list. All the other schools we registered her at she is either guaranteed a place or is on on the wait list. Does anyone know how likely she is to get a place at Cheam being registered at that age? I suspect, like Dragon (although we registered her there at 2 weeks and she was still only on the wait list), that it's going to be the wait list and won't know until much closer to the time. It's just that we are planning to move before she starts and we have a couple of target areas - the one we end up in will be based on where she is likely to go to school, so not knowing when we'll find out is a bit nerve wracking!
