Apply ESF Year 1 for 2008/2009

I want to apply year 1 for 2008/09 (for my child).
Refer to ESF instruction, the application period is 1 to 24 Sep 2007 and it will be prioritized by date of application.
If I post earlier (sharp on 1 Sep 2007), the chance is greater or not

Both I and my husband are Chinese and our child can speak both English and Cantonese because he studies in Bi-lingual class.
We want to apply Kennedy
School.
Anyone can tell me the chance?
How about last year?
Any similar case is success?
Thank you very much.
