Questions about the High School Diploma

All classes are taught in English and, with additional English language support, students are given the opportunity to develop strong English language skills.

The program allows you to study a range of subjects and gives you the right preparation for achieving a place at a top university or college in the United States.

Each of your courses will be given a GPA (grade point average) and this is the calculated average of the grades you receive from your courses. The U.S. GPA is on a 4-point-scale, with 4.0 being the equivalent of an ‘A’.

At CATS Academy Boston we do not weight our GPAs based on the level of course you take, as we know that every university and college will look at your application and individually assess it against its own entry criteria. Our College Counselors make sure you have the best possible application and include our School Profile Document to ensure Admissions Advisors can easily assess your level of achievement.

Most students take either one or two electives however, high-performing and able students may be considered to take more electives. This is reviewed on an individual basis.
