Hi
Hi there! How can I help you today?
What are you specialised in biochemistry or physiology or anatomy
I'm Orris, a general-purpose AI assistant, so I'm not limited to just one subject. Here's what I can help you with across all three areas:
Biochemistry
- Metabolic pathways (glycolysis, Krebs cycle, oxidative phosphorylation, etc.)
- Enzyme kinetics, protein structure, DNA/RNA, molecular biology
- Vitamins, cofactors, hormones at the molecular level
Physiology
- Organ system function (cardiovascular, renal, respiratory, neurological, endocrine, etc.)
- Homeostasis, feedback mechanisms, electrolyte balance
- Clinical correlations and pathophysiology
Anatomy
- Gross anatomy, neuroanatomy, embryology
- Regional anatomy (head & neck, thorax, abdomen, limbs)
- Histology and microanatomy
I also have access to a medical textbook library with authoritative references, so I can pull accurate, cited answers for detailed or complex questions - not just rely on general training knowledge.

- GeckoMed has the full archive from 2021-2025 with PYQ access
Important note: These are predictions based on patterns - not guaranteed questions. Always cross-check with actual PYQs from the official TNMGRMU site. Topics like hemoglobin, TCA cycle, urea cycle, beta-oxidation, and enzyme kinetics have appeared almost every year and should be your top priority.
So, I am preparing for my university exam, which is to be held on 27th July. So, I have 15 days, अ, till the exam and I have to revise 60 question papers. 20 question paper in biochemistry, 20 question paper in anatomy and 20 question paper in physiology. So, what should be, what should be my study plan from now onwards?
Here's your complete 15-day study plan, designed specifically for your situation:
15-Day Study Plan for TNMGRMU 1st MBBS (Exam: July 27)
Overview Strategy
- 60 papers across 3 subjects = ~4 papers/day
- Keep last 2 days (July 25-26) free for revision only
- So you have 13 active study days for all papers
- Daily study target: ~5 papers/day (to finish in 12 days, leaving 3 days buffer)
Phase 1 - BIOCHEMISTRY FIRST (Days 1-5: July 11-15)
Do biochemistry first while your brain is fresh and you have momentum
| Day | Date | Task |
|---|---|---|
| Day 1 | July 11 (Today) | Biochem Papers 1-4 (Proteins, Enzymes) |
| Day 2 | July 12 | Biochem Papers 5-8 (Carbohydrate metabolism) |
| Day 3 | July 13 | Biochem Papers 9-12 (Lipid metabolism) |
| Day 4 | July 14 | Biochem Papers 13-16 (Amino acids, Urea cycle) |
| Day 5 | July 15 | Biochem Papers 17-20 + Quick revision of repeated topics |
Phase 2 - ANATOMY (Days 6-10: July 16-20)
Most memory-intensive subject - do it in the middle so it stays fresh
| Day | Date | Task |
|---|---|---|
| Day 6 | July 16 | Anatomy Papers 1-4 (General anatomy, Thorax) |
| Day 7 | July 17 | Anatomy Papers 5-8 (Abdomen, Pelvis) |

| Day 9 | July 19 | Anatomy Papers 13-16 (Head & Neck, Neuro) |
| Day 10 | July 20 | Anatomy Papers 17-20 + Quick revision of diagrams |
Phase 3 - PHYSIOLOGY (Days 11-13: July 21-23)
Do physiology last - it has more concept understanding, easier to retain close to exam
| Day | Date | Task |
|---|---|---|
| Day 11 | July 21 | Physio Papers 1-7 (CVS, Respiratory) |
| Day 12 | July 22 | Physio Papers 8-14 (Renal, Nervous system) |
| Day 13 | July 23 | Physio Papers 15-20 (Endocrine, Blood, GIT) |
Phase 4 - FINAL REVISION (Days 14-15: July 24-26)
| Day | Date | Task |
|---|---|---|
| Day 14 | July 24 | Revise all Biochemistry high-yield topics + write practice answers |
| Day 15 | July 25 | Revise all Anatomy diagrams + Physiology flowcharts |
| Day 16 | July 26 | Light revision only - go through headings, no new topics |
Daily Routine (Each Study Day)
6:00 AM - Wake up, freshen up
6:30 AM - Session 1 (2.5 hrs): First 2-3 papers of the day
9:00 AM - Break + Breakfast
9:30 AM - Session 2 (2 hrs): Next 2 papers
11:30 AM - Short break
11:45 AM - Session 3 (1 hr): Write down repeated questions/answers
1:00 PM - Lunch + Rest
2:30 PM - Session 4 (1.5 hrs): Review what you studied in the morning
4:00 PM - Break
4:30 PM - Session 5 (1.5 hrs): Make quick notes / short answers
6:00 PM - Light walk / relax
7:30 PM - Session 6 (1 hr): Read previous day topics (spaced repetition)
9:00 PM - Dinner
10:00 PM - Sleep (8 hrs minimum - memory consolidation happens during sleep)
Smart Tips for Each Subject
Biochemistry:
- Don't memorize every step - understand the logic of each pathway
- Draw pathways as diagrams (TCA, urea cycle, glycolysis) - faster to recall
- Keep a list of "repeated questions" as you go through papers
Anatomy:
- Always draw the diagram first, then write the answer
- Group by region - don't jump between unrelated topics
- Use colored pens for nerve/artery/vein coding
Physiology:
- Use flowcharts for mechanisms (e.g., BP regulation, filtration)
- Link clinical conditions to mechanisms (e.g., heart failure -> starling's law)
- Short notes are your best friend here
What NOT to Do
- Don't study all 3 subjects on the same day - it causes confusion
- Don't skip sleep to study more - counterproductive
- Don't start new reference books now - stick to your existing notes + PYQs
- Don't panic if you miss a day - the buffer days exist for this
You have a realistic and achievable plan. The key is consistency over intensity - 8-9 focused hours daily beats 14 hours of distracted studying. Good luck for July 27! 💪
