Kumon~~!! I found the advertizing of Kumon in a magazine here ~~!!
I was a student of Kumon when I was a junior high and high school student (for 6 years). After graduating from my high school, I came back to Kumon as an assistant for one year. That's why I was so excited when I found it.
I think Kumon is not so popular for high school students, because teaching materials of Kumon are not related directly to entrance exams for universities. So, (in my opinion) most students (parents?)prefer juku schools to get direct strategies to pass entrance examinations.
But, I am a fan of Kumon~~ , because the way of studying of Kumon really suited me. In Kumon, we can choose materials suit our own levels without concerning our grades in our schools. I was a really slow learner( and I am still a slow learner..) especially math...( Math is my enemy...) My teachers and my parents said so , so the fact I was a slow learner is the unshackable fact..(' ';) So, Kumon was good environment for me to study without pressure~~
By the way, Kumon was the first place I studied English. That's why I like English, probably~~
