I have just received email today from RC telling us that they are sending out the invitation letter for interview, they said we should be able to receive the letter by end of this week...
don't be panic.
That is the rule of game.
ESF kinder applicants have higher priority than non-ESF kinder for interview but most of them will be going to ESF Primary (instead of RC) eventually.
While waiting patiently, think about contingency plans.
