Now I have enough information to build a comprehensive, well-structured 30-day pharmacology study guide. Let me compile it.

High-Yield Topics (Never Skip)
These topics are almost universally asked in MBBS exams and MCQ-based PG entrance tests:
- Drug receptor types and signal transduction
- Organophosphate poisoning and treatment (atropine + pralidoxime)
- Beta blocker cardioselectivity and contraindications
- Heparin vs. warfarin (reversal agents, monitoring, uses)
- Antimicrobial resistance mechanisms
- SSRIs vs. TCAs vs. MAOIs (side effect profiles)
- Epilepsy drug of choice in different seizure types
- Insulin types and peak action times
- Drugs contraindicated in pregnancy (Category X)
- NSAIDs mechanism + GI/renal side effects
Daily Routine Template
Morning (2 hrs): Watch 1-2 YouTube lectures on today's topic
Afternoon (1 hr): Read KD Tripathi chapter - highlight key drugs/mechanisms
Evening (1 hr): Make 1-page notes (mechanism table, side effects, uses)
Night (30 min): Solve 15-20 MCQs on the day's topic
Weekly (Day 7): Cumulative MCQ sprint (50-100 questions, timed)

Exam Strategy Notes
- Short questions (2-5 marks): Know mechanism of action, one clinical use, and one important side effect for every major drug.
- Long questions (10 marks): Be ready to compare drug classes (e.g., "compare heparin and warfarin," "classify antiepileptics with mechanisms").
- MCQs: Focus on drugs of choice, contraindications, and antidotes - these are the most tested patterns.
- Mnemonics: Use Sketchy Pharm (free YouTube samples) or make your own. A table of "drug - MOA - use - side effect" is more exam-efficient than re-reading paragraphs.
This plan covers the full standard MBBS pharmacology syllabus in 30 days at roughly 3-4 hours per day. If you have less time on any day, prioritize the MCQs and your one-page note over re-watching lectures - active recall beats passive review every time.
