Online School FAQs

Can I do online school instead of traditional school?

Yes, at Crimson Global Academy we offer a range of internationally accredited courses for full-time enrolment. We have enrollment options for primary students (aged 8-10), lower secondary students (aged 10-13) and high school students (aged 13-18). Our students attend a minimum of 19 hours of classes a week and have access to a full range of extracurricular activities as well as university counselling.
Speak to an advisor to get started.

What's the difference between part-time and full time enrolment?

Part-time CGA students attend a traditional school and study 1-2 subjects with CGA outside of their regular school hours. For full-time students, CGA is their only school.

Are your classes interactive and live?

Our synchronous classes are delivered live, in real-time. Students participate in small, discussion-based classrooms that are optimised for learning and engagement.

How will I know my child is being taught and interacting in the classes?

The CGA Parent Portal allows parents to access in depth information about their child's workload, progress and feedback, along with a seamless connection to those who matter in their educational journey.
You can read more information here.

Do you only cater to advanced students?

Not at all. While roughly 30% of students are studying at least one subject above their grade level, 40% of students are studying at their grade level and some are studying below their grade level in order to catch up. Every student at CGA has different needs and enrols in CGA because they understand its benefits and want to be there to learn.

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.

How can I enrol for online school?

Enrolling at CGA is easy. We offer both full time and part time options for students aged between 8 and 18 across  International GCSE, A Levels, AP curriculum, and the US Diploma.
Speak to an advisor to get started.

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.
