Thanks Mommy A-N-N and meki for the helpful insights. I decided to enroll my son in INGENIUM a progressive school in Marikina too. I learned that one of the founders is a Jesuit priest who graduated from Ateneo - gradeschool to college and even taught at the said University. I also got impressed with their curriculum and high passing rates in BIG schools. My first choice was ISYC since I really got impressed with their student ratio and facilities. Sadly it was already closed. I was told that it mostly get filled up by January. But I guess God has planned us to be destined for INGENIUM

Here are some updates I got for SY 2014-2015:
ISYC > Tuition is at 78K, all inclusive of materials, fields trips, 4 sets of uniform. Food is not included
> Enrollment is now CLOSED. Slots got filled up early, so make sure to reserve for next
school year as early as January
> When you call and asked to be wait-listed, don't bother, coz they do not call/text you on the
day they said they would. You have to make several follow ups to get a decent answer.
> School is guarded, but I don't like the setup that its not gated.
> for school bus service, there are several posted at the entrance
> have impressive passing rates to BIG schools
> student ratio is 1 teacher to 5 kids
INGENIUM > tuition is at 82-84k depending on level, inclusive for field trips and 2 sets of uniform.
Books are extra less than 2k
> Enrollment is still OPEN. They still have a few slots left, and will be opening another
afternoon class if necessary.
> School is guarded and gated.
> have impressive passing rates to BIG schools
> student ration: 2 teachers for 12-15 kids plus 2 yaya helpers
Tip in INGENIUM, visit the school and have your kid assessed for 350 pesos. After that, if you are decided you can pay the reservation of 4000 just as not to lose the time slot you prefer.
I also visited other preschools but did not like the location and school grounds.
