A Level Computer Science Quiz 2021 Part 1

15 Questions

Quiz Description

Computer science is the study of the theoretical foundations of information and computation and of practical techniques for their implementation and application in computer systems.

The advanced level syllabus for computer science is very broad and often discourages students. But “there is a saying that variety is the spice of life”, and it certainly helps to improve your studying.

Students are fun doing the same things such as reading notes on a subject over and over. It is always good to try different ways of studying. To spice things up for students, we have put together a quiz made up of 15 questions. Topics relating to questions include “data structure and algorithm. Information system.

This quiz will help students determine where they left out details, gabs and from there, they can go back and revise.
