1. Understand, do not memorize — Examiners ask follow-up questions to test depth of understanding.
2. Connect theory to practice — Always be ready to write a SQL query or draw an ER diagram on the spot.
3. Use correct terminology — Use terms like "relation", "tuple", "attribute" instead of "table", "row", "column" where appropriate.
4. Explain with examples — For every concept, have a real-world example ready.
5. Know your lab programs — Be ready to explain any code from your lab file.
