Programming for the Exam — Python Answers That Score

The programming half of the paper, taught at exam pitch. Pseudocode translated both ways, because the mark scheme is written in a notation nobody practises. Trace tables done column by column, including the ones with a loop and a condition inside it. Linear and binary search, bubble and insertion sort, what each costs and the comparison questions boards love. Validation against verification, and the boundary test data everybody forgets. Procedures against functions, and a systematic method for finding your own error with four minutes left.

Programming for the Exam — Python Answers That Score

Briffing

A learner sat down with me having written working Python for a year and having scored badly on every programming question he had ever attempted. Nothing was wrong with his code. The exam had never asked him for code. That is what this segment fixes. Exam boards mark pseudocode, not Python, and the notation is theirs — with ENDIF and ENDWHILE and an inclusive FOR i ← 1 TO 5 that means something quietly different from range(1, 5). Nobody practises the translation, everybody assumes their Python habits will carry, and the habits do not carry. So you will translate in both directions until it is dull. You will rule trace tables with an actual ruler and fill them a line at a time, including the rows where nothing changes — which is where the marks are and which is the first discipline to go under time pressure. You will trace a binary search on paper and count the comparisons, then answer the question boards keep asking: is it worth sorting a list of a thousand items so you can search it once? You will sort index cards with your hands before you write a sort in code. And you will learn to find a fault in your own program by halving it, systematically, rather than by reading it again harder — because a systematic method still works when you are frightened and reading harder does not. Every module ends with a timed drill marked the way an examiner marks it: what earns the mark, and the answer that looks right and earns nothing. Prerequisite: you can already write small Python programs — variables, if, loops, def, input(). This segment does not teach the language from zero. If it is still new, do Python From a White Sheet first; it is free and it is the exact sequence this one assumes. Written against the published topic lists for CAIE IGCSE 0478 and the UK GCSE Computer Science specifications, with notes for IB. The boards differ here more than anywhere — especially on pseudocode conventions, and on whether arrays are indexed from 0 or from 1 — and where they differ this segment names the difference and sends you to your own specification. Every question is original and modelled on the shape of exam questions; no past paper, mark scheme or specification text is reproduced, and Korra Academy is not affiliated with, or endorsed by, any exam board.

01 Their Notation, and Your Table
3 lessons·1h 35m

The exam does not mark Python. Almost none of them do. You will sit a paper written in a notation that looks like BASIC assembled by a committee, and the mark scheme is written in it too. Two jobs,…
02 The Structures They Give Marks For
3 lessons·1h 40m

Three separate IF statements are not an ELSE IF chain, and reversing the order of the conditions breaks it a second way. Both are one-line bugs, both are favourite exam questions, and both run…
03 The Standard Algorithms
3 lessons·1h 40m

This module is done with your hands first. Numbered cards on a desk for the halving, a row of cards for the bubble pass, a hand of cards for the insertion. Every one of these algorithms was a…
04 Subprograms, Testing, and Your Own Errors
3 lessons·1h 43m

Python has one keyword, def, and the exam has two things with two keywords. The whole distinction is one question: does a value come back to the place that called it? Learners who only write Python…

Mwy yn Rhaglennu

Beginner Python From a White Sheet The exact sequence nine students have already walked, from a blank file to a program that asks questions, checks the answers and refuses bad input. No prior programming. No maths. You will break it repeatedly, on purpose.

Beginner Binary, Hex and Data Units The topic that costs more marks than any other on the paper, taught by hand. Bits and bytes, binary and hex in all six directions, the 1000-versus-1024 trap, file sizes, transmission times, overflow, two's complement and character sets. Every module ends in a timed drill marked the way an examiner marks it.

Beginner AI Without the Hype What the model is actually doing when it answers you, why that produces something that looks like thinking, why it invents citations, and the cost mechanic almost nobody explains: a chat resends the entire conversation on every single turn. You will do the arithmetic yourself.

Beginner First Program — Scratch for ages 5–9 Nine Scratch blocks, three sessions of about twenty-five minutes, and one small program a child of five to nine builds themselves. Written for the parent sitting beside them: what to click, what they will get stuck on, what to say when it goes wrong, and when to keep your hands off the mouse.

Intermediate IGCSE and GCSE Computer Science — Theory That Actually Gets Marked The theory half of the paper, taught so it survives the exam room. The memory hierarchy and what actually happens at boot. Compilers, interpreters and assemblers, including the answer that sounds right and scores nothing. Databases from a spreadsheet up to keys and normalisation. DNS and the full path between pressing Enter and seeing the page. Systems software, and the ethical and legal section that is the easiest ten marks on the paper.

Beginner IT Support, Properly For the person who was hired to do one job and is now the one everybody rings when the printer stops. Windows, accounts, logs, networking and the two sabotaged printer rounds, built so you can rebuild every fault yourself on a VM.
