Stop hunting for pseudocode practice. This is the whole programme in one workbook.

Pseudocode Mastery gives you 100 exam-style tasks written in the OCR Reference Language, with complete model answers, mark schemes, marking guidance and common mistakes for every task. It is built for OCR GCSE Computer Science J277 and is ready to print or use on screen.

WHAT YOU GET

100 tasks and 510 marks across five levels of progressive difficulty
Complete model answers for every task
A mark scheme for every task, with marks shown in square brackets
Teacher marking guidance for every task, including what to accept and reject
Common mistakes for every task, so you can pre-empt misconceptions
A final OCR-style pseudocode quick reference sheet with syntax, examples and command words
A task index and skills coverage map showing exactly which tasks cover which skills

FIVE LEVELS

Level 1 – Fundamentals (Tasks 1–20): variables, constants, assignment, INPUT and OUTPUT, data types, casting, operators and strings
Level 2 – Selection and Iteration (Tasks 21–40): IF, ELSEIF, ELSE, CASE, FOR, WHILE, do…until, nested structures and validation
Level 3 – Arrays, Strings and Boolean Logic (Tasks 41–60): 1D and 2D arrays, string handling, ASCII, truth tables, validation types and linear search
Level 4 – Algorithms and Problem Solving (Tasks 61–80): bubble, insertion and merge sort, binary search, functions, procedures, scope, file handling and random numbers
Level 5 – Examination Challenges (Tasks 81–100): extended 6 to 12 mark questions, debugging, efficiency and a full exam-style finale

EVERY SKILL STUDENTS NEED
Students complete, write, trace, correct and explain pseudocode, predict output and convert written problems into algorithms. Trace tables, debugging and algorithm design are built in from the start.

STRICT J277 RELEVANCE
All code follows OCR Reference Language conventions consistently. Syntax from other boards appears only in one clearly labelled comparison table, so students are never confused.

PERFECT FOR

Paper 2 practice and programming skills revision
Homework, cover lessons and independent study
Intervention and catch-up groups
Starters, plenaries and assessment preparation

Professionally designed, with colour-coded task types, dark code blocks and clear layouts, so it looks as good on a desk as it does on a screen.
