Cambridge exams (0478, 2210, 9618) do not test you on Python, Java, or C++ during your written Paper 2 exams. Instead, they test your understanding of pure logic using a standardized, language-independent syntax called Pseudocode.
The biggest mistake students make is writing "Syntax Soup"—accidentally using Python shortcuts instead of strict pseudocode. Our interactive guides and cloud compiler will train you to write the exact format examiners are looking for.
If you learned Python first, you are likely losing marks on simple syntax errors. Here are the core differences you must memorize:
| Concept | 🐍 Python (Wrong for Exams) | 📘 Cambridge Pseudocode (Correct) |
|---|---|---|
| Assignment | score = 10 | Score ← 10 |
| Declaration | (Not Required) | DECLARE Score : INTEGER |
| Equality Check | if score == 10: | IF Score = 10 THEN |
| Array Indexing | Starts at 0 | Starts at 1 |
