2. SQL (20 Marks)

3. Networks (10 Marks)

  • Tip: Free marks if read once.

Avoid These Mistakes ❌

Indentation Error

Python hates bad spacing. Always align your if, else, and loops correctly in exam copy too.

SQL Constraints

Forgetting PRIMARY KEY or NOT NULL cuts marks. Read the question constraints carefully.

File Modes

Confusing w (write) with a (append). This changes the entire output.
