Canadian International School

Any comments for this school Is it hard to get in ? I'm not so familiar with IS, but start to think of it because my son is very active and I'm feeling the pressure for doing homework and revision is getting to harm our relationship. Almost all my friends think he would be better off in IS than local school (demanding one), although local school was our original plan. He will go to P1 in coming Sep, my plan is to let him (or me) try in local school first, and if things not going in right track, we need to make the decision to switch in P2 or P3.
