So, you are waiting for St Jo to release result tomorrow (presumably you had 2nd interview with the Principal). If you get an offer from St Jo, you are likely to accept that offer, right? It seems waste of time in the first place if St Jo, in your view, is not better than YW.
I think ur son got both offer of YW & SFA and then u knocked the door of St Jo.
But the result of St Jo will be released on 2/7. Why you know the result so early.
BTW, when will you give up the offer of YW & SFA??
