✅ TO SCORE 80+: The Non-Negotiable List
For every starred topic, make sure you can write:
- Classification (always asked - even for MCQs)
- MOA in 2-3 sentences
- Key uses (with doses where famous - e.g., aspirin 75mg antiplatelet)
- Side effects - especially the "unique" ones (e.g., gingival hypertrophy = Phenytoin, agranulocytosis = Clozapine)
- Antidote if applicable
- One clinical scenario relevance
Focus your last 2 weeks on Tier 1 topics (6 topics). They alone can get you 60-65 marks based on PYQ frequency. Tier 2 takes you to 80+.
