Sorry to here your DD didn't do as well as you had hoped in her 11+. Details of the WCC appeals process can be found here - http://www.warwickshire.gov.uk/schoolappeals
- but you won't be able to do anything until March after national offers day.
For now, complete your CAF putting Shottery first so that you can be turned down in March and then be able to appeal that decision. In the meantime, collect as much evidence as you can proving your DD's academic ability to support your appeal. A word of caution though, appeals for the Stratford grammars are very rarely upheld I'm afraid.
Best of luck,
