To be honest compare with other IS, $500 application frees is really affordable. Anfield is $800 / FIS is 2800 and they both never guarantee interview must be provided
I am one of those who applied for ESF Wu Kai Sha, paying the $500 application fee yet without an interview chance. I think ICS arrangement is so much better, though the fee is double. ICS applicants are required to submit a $1000 cheque when you attend the interview.
We paid $2000 application fee and didn’t get any interview for cis too but I understand it’s how the system works, anyway we spent 2 years at esf kindergarten and it’s a waste of time, we rejected esf primary offer and picked another school finally
