since the heading of the post is MS vs GH, I have miss another reply for talking about SC, and you say don't like SC, I think you are talking about MS, sorry for misunderstanding.
My daughter got accepted by the E/P class of MS, too. Same as you, we are waiting for Good Hope which obviously is a more decent school. We think MS is very good but trust Good Hope is better. Our daughters may be in the same class in the future. 請多多指教!!
