National Eligibility cum Entrance Test (UG)

NEET UG is the single entrance test for undergraduate medical, dental and allied courses across India. It is conducted by the National Testing Agency, once a year, and — unusually for an exam of its size — still on paper.

Biology carries half the paper — 90 of the 180 questions, 360 of the 720 marks, split evenly between Botany and Zoology. Physics and Chemistry take 45 questions each. Any study plan that gives the three subjects equal time is already misallocated.

The OMR sheet is part of the exam

A computer-based test forgives a changed mind; an OMR sheet does not. Bubbles must be filled completely, in the correct pen, with no stray marks, and a mis-shift of one row corrupts everything after it. Practise on real OMR sheets until filling them is automatic — candidates lose marks here every year for reasons that have nothing to do with medicine.

In NEET, accuracy matters more than attempts

180 questions in 180 minutes works out to a minute per question, so time is tight but manageable. The real constraint is accuracy. Every wrong answer costs you five marks in effect, and near the top of the NEET list five marks can be the difference of several thousand ranks.

Work out the arithmetic yourself: a student who attempts 160 questions with 95% accuracy finishes ahead of one who attempts all 180 with 85%. Knowing which twenty to leave is something you learn in mock tests. You cannot work it out for the first time on exam day.

Ties

With so many candidates and a 720-mark ceiling, identical scores are common. Published tie-breaking rules resolve them — in recent cycles working through subject-wise performance and the proportion of incorrect to correct answers, before falling back to other criteria. Another reason a blank is safer than a guess.

Academic requirement

You must have passed, or be appearing for, Class 12 with Physics, Chemistry, Biology or Biotechnology, and English. Biology taken as an additional subject is accepted.

Minimum aggregate in Physics, Chemistry and Biology taken together:

Age

You must be at least 17 years old by 31 December of the year of admission. There is no upper age limit, and no limit on the number of attempts.

Studying medicine abroad

Indian nationals intending to study medicine outside India also need to qualify NEET — it is the basis of the eligibility certificate required for a foreign primary medical qualification to be recognised on return. Sitting NEET is not optional simply because your plan is an overseas university.

The syllabus follows NCERT Class 11 and Class 12 in Physics, Chemistry and Biology. For Biology in particular, the NCERT text is not a recommendation — it is effectively the source document, down to individual sentences and diagram labels.

Biology — half the paper

Class 11 covers diversity of living organisms, structural organisation in plants and animals, cell structure and function, plant physiology and human physiology. Class 12 covers reproduction, genetics and evolution, biology in human welfare, biotechnology, and ecology. Genetics, human physiology and ecology are reliably heavy scorers.

Read the NCERT line by line, including the summaries, the boxed asides and the diagram captions. Questions are drawn from all of them.

Chemistry

Physical chemistry rewards practice: mole concept, thermodynamics, equilibrium, electrochemistry, solutions. Inorganic chemistry is close reading of NCERT — periodic properties, chemical bonding, the p-block, coordination compounds. Organic chemistry runs from general organic chemistry through hydrocarbons to the functional-group chapters and biomolecules.

Physics

Usually the section candidates find hardest, because it is the one that demands calculation under time pressure. Mechanics, thermodynamics, oscillations and waves, electrostatics and current electricity, magnetic effects, electromagnetic induction, optics, and modern physics. Do not write it off — it is 180 marks, and a Biology-only strategy caps your rank hard.

NCERT Biology is your main book, not a reference

In no other Indian entrance exam is one textbook this close to being the syllabus itself. Read it several times, and make each reading more active than the last — read a section, close the book, recall it aloud or on paper, then open it again and see what you missed. Keep the reference books for question practice. They do not replace NCERT.

Do not leave Physics for later

The pattern we see every year is a student who is strong in Biology, manages Chemistry, and keeps hoping Physics will somehow work out. It does not work out by itself. Physics is 180 marks and it is where ranks actually separate. One hour a day of problem-solving from Class 11 is worth far more than one panicked month at the end.

Get accuracy right first, speed comes after

Because of negative marking, your first target is getting a high percentage right out of whatever you attempt. Speed builds on its own as chapters become familiar; it cannot be forced before that. Note your accuracy subject-wise after every mock, and treat a drop in accuracy as a bigger warning than a drop in attempts.

Practise on an actual OMR sheet

Full 180-question papers, three hours, with a real answer sheet in front of you. Part of it is stamina and part of it is the mechanics — filling bubbles properly, keeping track of the row number, deciding when to move on. None of this can be practised on a screen, and every year students lose marks here for reasons that have nothing to do with Biology.

Plan for three rounds of revision from day one

The syllabus is far too large to hold in your head after one reading. Decide at the start that you will go through it three times: once thoroughly, once with questions alongside, and once quickly from your own notes. Students who plan three rounds finish them. Students who plan one and keep revision for the end do not.

Maintain a mistake register

One line per mistake — what it was and why it happened. Read it once a week. For most students the same twenty or so misunderstandings cause the bulk of the losses, and writing them down is usually what finally fixes them.

NEET seats are allocated through two parallel processes, and you generally need to be registered in both to keep your options open.

All India Quota — the Medical Counselling Committee

The MCC conducts counselling for the 15% All India Quota in state government colleges, and for seats at central universities, deemed universities, AIIMS, JIPMER, ESIC and AFMC. It runs in rounds, with a mop-up and a stray-vacancy round at the end.

State quota

The remaining 85% of state government college seats are allocated by each state's own authority, under its own domicile rules and its own timetable. Private colleges within a state are usually part of that process too.

The two calendars overlap but do not align. Registering for one does not register you for the other, and a missed state registration cannot be recovered through MCC.

Courses NEET admits you to

• MBBS and BDS
• AYUSH courses — BAMS, BHMS, BSMS, BUMS
• BVSc & AH (veterinary)
• Certain BSc Nursing and allied health programmes, depending on the institution

How many times is NEET held each year?

Once. Unlike JEE Main there is no second session, which makes the single attempt heavier and makes mock-test discipline more important.

Is there an upper age limit?

No. You must be 17 by 31 December of the admission year; there is no ceiling and no cap on attempts.

Can I take NEET with Biology as an additional subject?

Yes. Biology or Biotechnology studied as an additional subject is accepted, provided the subject and percentage requirements are met.

Do I need NEET to study MBBS abroad?

Yes, if you are an Indian national and intend to practise in India afterwards. NEET qualification underpins the eligibility certificate for a foreign medical degree to be recognised.

How much of the paper is Biology?

Half — 90 of 180 questions and 360 of 720 marks, split between Botany and Zoology.

Is NCERT enough for Biology?

For the content, largely yes, and it should be your primary text. You still need substantial question practice from elsewhere to convert that knowledge into marks under time pressure.

What happens if two candidates score the same?

Published tie-breaking criteria apply, working through subject performance and the ratio of incorrect to correct answers before other factors. It is another reason to leave a question blank rather than guess.
