What you'll learn

• 1GCSE exam papers use specific command words like state, describe, explain and discuss, and each one tells you how detailed your answer should be.
• 2You need to be confident converting between binary, denary and hexadecimal quickly, since many exam questions test this under time pressure.
• 3A trace table helps you follow what happens to variables step by step as a program runs, which is useful for checking your understanding of code.
• 4Pseudocode is a way of writing out an algorithm in plain, structured English-like steps, without worrying about the exact syntax of a real programming language.
• 5Exam papers also include scenario based questions on networks and security, and you should manage your time so that harder or longer questions get enough attention.
