Theory of computer science IGCSE (Standard 9 to 12, O-level to A-level)

In this course student will be able to understand the behavior of hardware, understand the integration of hardware and the software. We provide every assistance to the student to understand each topic and master the topic by practicing the exercise given by us. We help student to solve Problems as well as Programming pre-release material given by the board.

Here at Sigma-Pi Academy, Video recording of every class and pdf of class notes will be provided. Regular tests will be taken and we would work on the weakpoint of the student. Doubt clearing at the time when the student is unable to solve the problem.
