How much does online school cost?

CGA offers a pay-per-subject fee structure. This means that each student has a tailored fee structure based on their enrolment options as well as the number of subjects they elect to take. Learn more about our fees here.

Can high school students take online college courses?

Advanced Placement (AP) courses are college-level classes that US high school students take. A good score in the AP exams can translate into college credit as well.

CGA offers part time AP classes - which means you can take them in the evenings or weekends to secure college credit while in high school.

How do I enroll for online high school?

Enrolling at CGA is easy. We offer both full time and part time options for the International GCSE, A Levels and AP curriculum. Speak to an advisor to get started.

Can you start online school anytime?

At CGA we offer flexible enrolment options with two major intakes - in January and September - each year. If you want to join outside of these intake times, speak to an advisor to learn more.

Do universities accept online high school diplomas?

Most universities worldwide accept international curricula like the GCSEs and A Levels. At CGA all our students graduate with an academic transcript that can be submitted for applications to global universities. However, you should still check with your university about particular admissions criteria.

Can you graduate high school early online?

If you are ready to accelerate ahead of your traditional school year, you might be able to complete high school early. However, many schools do now allow students to accelerate.

At CGA, you study to your ability, not age. By taking classes and exams based on your ability, you could accelerate past the traditional school age to graduate early. Speak to an advisor to find out more.
