Thank you so much for your advices. It gave me a better idea on how I should start. And yes, I am also aware that the registration for P1 in 2011 is in mid 2010
That's why now I am ready (kiasu) to become a PV kekeke.
Actually though I was a former student from OEPS, the distance travelling could pose a problem at times. Why I said that is because:
1) Actually I am residing in Sengkang now BUT we have businesses running in Siglap so that's not too bad. But then again, sometime working hours might clashes. Having said that, the hours for preparation to school will also have to be planned even earlier.
2) We have plans to buy a private estate around that area (if our business for the next 1 year is very huat lah haha) but then it's not something concrete and confirm so back to point 1 that is my main concern.
In fact CHIJ's distance is nearer to us compared to OEPS. My parents house is also in Sengkang so in any case that I am unable to send or fetch, it's easier to get help from them 
As for my son's future P1 registration, my husband already has plans to send him to St. Andrews cos he was a former student there 
So that's why the 3 choices of schools and the confusions! OEPS has a higher chance of getting a placing but distance, NanChiau is absolutely fine, near to my place (and my mum's), good grades and reputation (and I'm a hokkien!) but some how the enthusiam is not there if you know what I mean and finally CHIJ, well like her to be one-gender school cos she likes to play rough and the boys at kindergarten also likes to play with her so hope she could be more feminine after going there (silly rite hahaha). And most of all, I appreciate biblical teachings even though I'm a free thinker.
I'll show my husband tonite on all your kind advices then see what the man says lor hahaha
Oh and so sorry, I will report my \"enrollment\" in the newbie thread
