| | Action | Benefit | | :--- | :--- | :--- | | 1 | Collect papers from 2016 onwards (CBCS pattern). Pre-2016 papers are under old syllabus (1+1+1 system) – useful only for basic concepts. | Avoids studying irrelevant topics. | | 2 | Make a frequency chart : Count how many times "Crystal Field Theory" appears vs "Molecular Orbital Theory". | Identifies high-yield chapters. | | 3 | Time yourself – CU exams are 2 hours for 40 marks. Practice finishing Group C (long answers) in under 25 minutes. | Improves speed & time management. | | 4 | Compare General (GE) papers with Honours (CC) papers – GE papers are easier but sometimes the same topics appear in both. | Helps GE students score well. | | | Action | Benefit | | :---
