Welcome back to our OCR GCSE Computer Science (J277) revision series! Today, we are focusing on designing logic visually. We will master standard flowchart symbols, learn how to structure complex problems, and translate visual logic into pseudocode for Paper 2.
We will use interactive visualisers to cover:
- Flowchart Symbols: The 5 essential shapes you must know (Terminal, Process, Decision, Input/Output, and Sub-program).
- The Logic Visualiser: A live side-by-side run of a Flowchart executing alongside its matching Pseudocode.
- Structure Diagrams: Using Top-Down Design to break an ATM system into manageable modules.
- Nesting: How to place programming constructs (like IF statements) inside one another.
- Challenge Zone: We step back into Examiner Audit Mode to live-mark a Pseudocode-to-Flowchart drawing, and identify a sneaky Syntax error!
