自動車保険の優秀学生割引
アメリカの自動車保険には「Good Student Discount」という割引制度があるようです。
GPA（grade point average）が3.0以上の学生の場合、最大で25％も割引になるというのです。

Good Student Discount
Full-time high school, college or university students (minimum of 12 units per term) with less than nine years of driving experience who have attained a current or cumulative grade point average (GPA) of at least 3.0 are eligible for a discount of up to 25 percent* on some coverages carried on the vehicle(s) on which they are rated as primary or occasional drivers. Current GPA takes into account only coursework completed in the most recent academic term; cumulative GPA takes into account all coursework completed at the student's current academic institution. Acceptable certification of full-time student status and grade point average must be submitted to us to obtain the discount.
