Both sections to be answered in the same book.
Equivalence of paper titles and content is not applicable under the new syllabus.

Special Instructions

No special instructions at the initial stage; suggestions will follow implementation.
Fieldwork, seminars, group discussions, and oral examinations to be detailed as needed.
Laboratory safety instructions must be provided where applicable.

Laboratory Safety and Equipment

Personal Precautions: Safety goggles, lab aprons, and proper footwear mandatory. Over-hurried activities restricted; eating, drinking, and smoking prohibited.
Safety and Emergency Equipment: First aid kits, fire extinguishers, chemical storage cabinets, and material safety data sheets required.
Local Exhaust Systems: Proper management of fume hoods is essential; sign-in register for instrument usage.

Academic Credit System

Credits represent student workload across various activities: lectures, practicals, seminars, private work, examinations, and assessments.
Each student faces 24 hours of examination time per semester: 12 hours for theory and 12 hours for practicals.
Course structure includes minimum two seminars per semester, library work, and a weightage system emphasizing external assessments.

Credit Distribution for Theory and Practicals
