2D Arrays: Totals & Averages Explained | Cambridge IGCSE / Olevel / A Level CS

In this video, you’ll learn how to calculate totals and averages using a 2D array—a very common exam question in Cambridge Computer Science.

We use a 2D array to store student marks and then:

Calculate the total marks for each student
Find the average marks
