i have recently filled out forms for my childs secondary school admissions but the only problem is its not in the catchment area, i know for a fact my entry will get turned down and will have to appeal, does anyone have a any experience when going against the school board?

There are already many threads on here about this subject - use the search engine.

Check out my thread from 2 years ago, we went through appeals process.
