9/10GreatSchools RatingParent Rating AverageThis school will not support your children, especially if there slow learners or have any sort of difficulty understanding. Your kid will be outcasted by teachers to look stupid. Publicly scolding your children in fromt of class mates, unless your kid is in all ap and was born a scholar run the other way. The teachers here are looking for easy work, they want to teach a lesson once and thats it. If you cant pick it up well best believe youll be left behind and scolded for it.Other Review1y ago
