Do you agree that if a child is bright enough he or she can catch up and even outdo others later in primary school, and thus no need to invest in expensive private preschool? Or do you think it's better to build a strong foundation during preschool years so they won't lose out in primary school?

for me, preparatory period of the Child, public school will do, but you should discipline your Child regarding GMRC, but when their in College kindly put them to prestigious school like UP, Ateneo etc. save money when your child goes to. Public School in their preparatory period up to grade 12, based on my experience, college in exclusive school is a must because this will be their setting stage what they wanted to do in their future, in a competitive way, with different Ideas, unlike College Public School they have a mindset that education is the key to have a job etc. but don't really have a career goal. still or will depend on the Student/Person, or the way you raise you Children. Like in nursery period they always first ask what they wanted to be.
