Any chance of getting in Grade 2 in ESF ! or any other IS?

Hi all,

I am very anxious and worried about getting a spot for my 5.5 years old girl.
We are moving back to HK late July (still in Sydney now). I have applied KCIS, QBS and CAIS for her but she is on waiting lists only.

We are not wealthy and can't afford those very expensive schools.
Any other schools that you can think of that are more affordable?
I heard that there will be more chances for students withdrawing during July/Aug. Yes?

PLEASE PLEASE advise. Thanks in advance.
