This is the deck version of Brain Quest. We used it a few times with my siblings in the car, etc., but it's in good condition. I just noticed that a child wrote answers in pencil on 5 pages of one book. The Reading section is also substantial, and I recommend it for extensive reading, even for junior high school students who are not native English speakers. The good thing about their teaching materials is that you naturally learn English expressions that you don't get taught in school. It's also recommended for children in international schools.
