The software in the Goukaku Boy Series range (recalling the initials of the Game Boy brand with the Goukaku term, or "success" in Japanese) are not games. These are in fact adaptations of books and exercise books intended for students preparing for university and high school entrance exams. A full-fledged series in the Goukaku Boy, The Koukou Nyuushi Derujun collection brings together titles specifically dedicated to entry courses in the largest high schools in Japan.

Here, the title lists 350 English expressions that college students should know.
