My 15 yo daughter is starting Grade 10 this year. She is currently in a Sarasas school, I am hoping someone can give me some information as to the quality of education at Kasinthorn St Peter school, Nonthaburi

Haven't heard any negatives about it, can't say the same for Sarasas Schools, which approach the notorious category.  I used to go by St. Peter on the way to the old immigration office.  Not a good location, but looked ok.
