Biochemistry is a scoring subject in INI CET once you stop cramming pathways and start understanding the logic behind them, because most items test an enzyme step, a deficiency or a molecular event. These sample papers give you 15 focused questions per set, sized to the number of Biochemistry items you actually meet in the real exam.

- Conducting body and exam: AIIMS New Delhi conducts INI CET twice a year, for the January and July admission sessions.
- Paper format: 200 single-best-response MCQs in the full exam, of which Biochemistry carries roughly 10 to 15 questions.
- Marking: +1 for a correct answer, minus one-third mark for a wrong answer, zero for an unattempted one.
- Mode and duration: Computer-based test, 180 minutes total, with a fixed 45-minute window per 50-question block.
- Subject choice: Biochemistry is compulsory pre-clinical content threaded through the paper, not a separate optional section.
- Syllabus base: The MBBS Biochemistry curriculum covering metabolism, enzymes, vitamins, molecular biology and clinical biochemistry.
INI CET Exam Pattern and Marks Distribution 2026
Biochemistry questions sit inside the same 200-question paper, so the pacing you build here has to match the full test. Lock the pattern before you touch a sample paper.
- Total questions and marks: 200 MCQs for 200 marks in the full exam, each worth 1 mark.
- Biochemistry share: Roughly 10 to 15 questions, drawn from metabolism, enzymes, vitamins, molecular biology and clinical biochemistry.
- Blocks: 4 parts of 50 questions each, 45 minutes fixed per part, with no going back to a closed part.
- Negative marking: Minus one-third (0.33) mark per wrong answer, so avoid blind guesses.
- Time per question: About 54 seconds each across the full paper.
Key advice: Biochemistry rewards clean recall of rate-limiting enzymes and deficiency states, so revise those triggers, and do not lose time re-deriving a whole pathway when one step is being asked.
INI CET Biochemistry Sample Papers - Why Recent Papers Matter Most
Biochemistry in INI CET has shifted from rote pathway recall to applied, clinically framed and molecular items, and recent papers show that change most clearly. Practising the latest sets stops you from over-reading dead topics.
- Newer papers wrap a metabolic defect inside a clinical vignette rather than asking the enzyme name directly.
- Molecular biology and genetics, such as replication, PCR and gene mutations, appear more often than in older papers.
- Solving the last 3 to 5 years first shows the real depth expected, so you calibrate effort correctly for each area.
INI CET Biochemistry Chapter Wise Weightage - High Scoring Topics to Focus in Sample Papers
There is no official chapter split, but recall papers point to a stable set of high-yield areas. Use this table to steer your Biochemistry practice.
| Topic | Questions | Difficulty | What to Watch For |
|---|---|---|---|
| Carbohydrate Metabolism | 2 - 3 | High | Glycolysis, TCA cycle, gluconeogenesis and their rate-limiting enzymes |
| Lipid Metabolism | 2 - 3 | High | Beta-oxidation, ketone bodies, cholesterol and lipoproteins |
| Molecular Biology and Genetics | 2 - 3 | High | DNA replication, transcription, translation and mutations |
| Enzymes and Enzyme Kinetics | 1 - 2 | Moderate | Michaelis-Menten, inhibition types and isoenzymes |
| Vitamins and Coenzymes | 1 - 2 | Moderate | Coenzyme roles and classic deficiency diseases |
| Amino Acid and Protein Metabolism | 1 - 2 | Moderate | Urea cycle, transamination and one-carbon metabolism |
| Bioenergetics and Electron Transport | 1 | Moderate | Oxidative phosphorylation, uncouplers and inhibitors |
| Inborn Errors and Nucleotide Metabolism | 1 | Low to Moderate | Classic enzyme deficiencies and purine or pyrimidine disorders |
Note: Do not skip the inborn errors and nucleotide topics. Their single likely question is usually a one-liner linking an enzyme defect to a syndrome, which means a quick, near-guaranteed mark.
INI CET Biochemistry Sample Paper Video Solutions 2026 - Watch Before You Start Solving
A guided walk-through of real Biochemistry recall questions shows you how examiners turn a single enzyme step or deficiency into a clinical item. That pattern recognition is exactly what you want before your first timed attempt.
The video below discusses Biochemistry previous-year questions for the medical PG exams, covering the same high-yield areas these papers test, so it is a solid warm-up before you sit the set.

How to Use INI CET Biochemistry Sample Papers to Clear in First Attempt
These papers only pay off if you solve them like the real block and then dissect every miss. Follow these steps each time.
- Solve each 15-question paper in one 14-minute sitting with no pauses, matching the exam pace.
- Tag every question you were unsure about, even the correct ones, and revisit them separately.
- Keep an error log split by area, so you see fast whether metabolism, enzymes or molecular biology is your weak point.
- Redo only the wrong and flagged questions after 48 hours to confirm the concept stuck.
- Maintain a one-page sheet of rate-limiting enzymes and vitamin deficiencies, since these repeat often.
- Aim to lift accuracy first, then squeeze the time per question down.
NCERT vs PYQ Balance for INI CET Biochemistry Sample Papers
For Biochemistry the balance is between standard textbook depth and previous-year recall trends. You need both, but in the right ratio.
- Use standard Biochemistry texts to build the pathway logic, not to memorise every isolated intermediate.
- Use previous-year and recall questions to see which enzyme steps and defects actually get tested and how deep.
- When a sample paper question feels new, trace it back to the underlying pathway or regulatory step rather than rote-learning the answer.
- Spend roughly 60 percent of revision time on high-yield PYQ patterns and 40 percent on fixing weak basics.
INI CET 4 Week Biochemistry Preparation Plan Using Sample Papers
- Week 1: Solve Papers 1 to 3, build an area-wise error log and revise carbohydrate and lipid metabolism pathways.
- Week 2: Attempt Papers 4 to 6, focus on enzymes, vitamins and the urea cycle, and drill deficiency-based questions daily.
- Week 3: Take Papers 7 and 8 under strict timing, then spend two days analysing every wrong and flagged question, with molecular biology as the priority revision.
- Week 4: Solve Papers 9 and 10 early in the week, redo all logged errors, and keep the last 2 days for light revision only, no new topics.
FAQs on INI CET Biochemistry Sample Papers 2026
Ques.How many questions and marks does each INI CET Biochemistry sample paper carry?
Ans.Each paper has 15 single-best-response MCQs for 15 marks, sized to the number of Biochemistry questions you actually meet in the real exam. Solve it in a tight 14-minute sitting to build exam-matched pacing.
Ques.How many Biochemistry questions actually come in the INI CET exam?
Ans.Biochemistry contributes roughly 10 to 15 questions out of the 200 in the full paper, as part of the pre-clinical share. These sample papers keep the same 15-question load so your practice mirrors the real exam weight.
Ques.What is the marking scheme I should apply while solving these papers?
Ans.Award yourself +1 for a correct answer and subtract one-third of a mark for a wrong one, with zero for unattempted questions. Scoring this way keeps your practice score honest and close to your likely exam score.
Ques.Which Biochemistry topics should I focus on first for INI CET?
Ans.Prioritise carbohydrate and lipid metabolism and molecular biology, since these repeat the most and carry the highest weight. The vitamin, inborn-error and nucleotide one-liners are quick, high-return additions once the heavy pathways are solid.
Ques.Are recent INI CET Biochemistry papers more useful than older ones for practice?
Ans.Yes, the exam keeps shifting Biochemistry toward clinical correlation and molecular biology, which recent papers reflect best. Solve the last 3 to 5 years first, then use older sets only for extra concept coverage.
Ques.Where can I download the INI CET Biochemistry sample papers for free?
Ans.You can download all ten INI CET Biochemistry sample papers free from this Collegedunia page. Always confirm the current pattern and any notices on the official website, aiimsexams.ac.in.
