What makes me most satisfied with the mathematics single subject after I make up lessons in high school is the childlike innocence further education school! The class is very big, but the head teacher of each class keeps a close eye on it. Basically, whenever you have something, she will talk to you. They are all grandma-level people, very caring, and sometimes they are annoying, but they are really good to you ~
The teacher is very good. I was taught by a talented teacher ~ class is very interesting! The topic is difficult, but after one class, you can get many methods and examples! I'm not sure about tutoring, but the big class who makes up math alone recommends childlike innocence ~
