**** Programming Concepts & Pseudocode****

The pack that Covers variables, data types, all selection and iteration structures (IF, CASE, FOR, WHILE, REPEAT UNTIL), nested loops, string handling, and 1D/2D arrays — written in exact Cambridge IGCSE 0478/0984 pseudocode conventions. Includes a progressive PPT (simple to complex), 12 pseudocode-writing exercises building from single statements to nested array loops, a 25-question MCQ quiz, and complete worked solutions. This is the pack your students will come back to again and again before Paper 2.

1. Core Lecture — 28 Slides (PPTX)

Covers every sub-topic in syllabus order: Variables & Constants (DECLARE, CONSTANT, ←) · Five data types with examples · Arithmetic/Relational/Logical operators including DIV and MOD · Sequence programs · IF…THEN…ELSE…ENDIF · CASE…OF…OTHERWISE…ENDCASE · FOR…TO…NEXT · WHILE…DO…ENDWHILE · REPEAT…UNTIL · Loop comparison table · Nested selection (grade calculator with trace) · Nested iteration (multiplication table + validate 5 scores) · Combined nested example (count passes/fails) · STRING functions LENGTH(), SUBSTRING(), & concatenation · 1D and 2D arrays with declarations and traversal · Common array algorithms (max, count, linear search) · Complete temperature logger program · Exam tips, trace table technique, command words, conventions reference card, practice slide, and recap.

**** 2. Worksheet (DOCX)****

17 questions total across 5 sections: Sequence (Q1–3: sum/difference, km-to-miles, till program) · Selection (Q4–6: positive/negative/zero, theme park pricing, CASE calculator) · Iteration (Q7–9: times table with FOR, running total with WHILE, guessing game with REPEAT) · Nested/Arrays (Q10–12: 7-day temperature array, 2D marks array, complete grade system) · Array Traversal A–E (total, maximum, count passes, 2D row total, all product totals with grand total). All questions have graded difficulty (★☆☆ to ★★★) and answer spaces.

3. Activity (DOCX)

“Find the Bug” debugging challenge — three progressive activities: Activity A (card sort: 10 scrambled lines to reorder + 1 bug), Activity B (4 bugs in a nested IF program), Activity C (3 bugs in a WHILE loop). Includes full teacher instructions, timings, printable cut-out cards, and extension task.

4. MCQ Quiz (DOCX)

25 questions across Easy/Medium/Hard. Includes 6 “what is the output?” trace questions (the exam’s favourite style) covering FOR loops, WHILE, REPEAT, nested loops, and array algorithms. Topics covered: variables, data types, DIV/MOD, selection, iteration, strings, arrays, 2D arrays, and logical operators.
