General Instructions

• Questions should be clear, unambiguous, understandable and free from grammatical errors.
• Questions which are based on the same concept, law, fact etc. and which generate the same answer should not be repeated under different forms (VSA, SA, LA and NP).
• Questions must be set based on the blowup syllabus only.
