Upper School (IGCSEs)

IGCSE Computer Science


Students will develop their computational thinking and problem solving to develop computer-based solutions using algorithms and programming languages.

They will also be able to appreciate the ethical issues that arise with current and emerging computing technologies.

Additionally, Information representation, communication and Internet technologies, hardware, software development, and relational database modelling are studied.


Teacher assessments are continuous during LIVE TAUGHT lessons, marking of coursework and assignments and summative tests.


Homework will be given at the end of each week, usually in the form of researching key concepts, quizzes for recapitulation and subject related fun, completion of coursework.


Parents have 24 /7 access to all of their children’s coursework, grades and teacher feedback. Additionally parents can arrange consultations with teachers at mutually convenient times.
