ESF Kindergarten Tsing Yi - 2010 K1

Anyone is planning to apply for 2010 K1 in ESF K1 My husband and myslef are Hong Kong Chinese so that we will probably be in the non-native English speaking category. However, we only use English at home. I want to know if it is very hard for my son to get in ESF? Anyone had the same situation as me but got into ESF? Could you please share your experince? Thank you.
