From September 01 to October 14, 2022, all campuses of American Intercon School have started its summer and preparatory course for all registered students for the academic year 2022-2023. These learning programs are purposefully created to enable students to learn some basic subjects like Khmer, Maths, Physic and Chemistry. Moreover, it is also a good chance for students to get familiar with learning environment in the school, especially new students. Furthermore, they can learn more about school rules and get to know new classmates and teachers in various subjects. To be notified, the summer and preparatory courses will last for six weeks. Within this period, students who get the score below average will receive the second chance to do supplementary exam in order to move to the next grade.
