Quantum Mechanics (25% weightage)
Thermodynamics & Modern Physics (20% weightage)

Time Management Strategy

Preparation Phase: 10-12 months ideal timeline
Daily Study: 4-5 hours for physics optional
Exam Strategy: First 10 minutes for question selection
Answer Writing: 25 minutes per answer
Revision: Last 15 minutes for review
Smart question selection to maximize scores
Prioritize questions from strong topics first

Answer Presentation Techniques

Start with brief introduction of concept
Neat diagrams with proper labeling
Step-by-step derivations for formulas
Highlight final answer with box
Use bullet points for multiple aspects
Include relevant real-world applications

Underline key terms and results

Pro Tip from Sourav Sir:

"Focus on mastering 70% of the syllabus thoroughly rather than covering 100% superficially. In Physics Optional, depth of understanding in core topics yields better results than superficial coverage of the entire syllabus. Practice numerical problems daily and develop a systematic approach to theoretical questions. Remember, consistency beats intensity - regular study of 4 hours daily is better than 12 hours occasionally."
