Complete Subject Wise NEET Syllabus 2027: Physics, Chemistry, Biology Explained

Most NEET aspirants don't struggle because they can't study. They struggle because they don't know what to study first, or how much of it actually matters for the exam. Three subjects, two years of NCERT content, and no clear sense of priority — that combination is enough to make anyone feel stuck before they've even opened a book. A syllabus solves that problem, provided you actually treat it as a working document instead of something you read once in June and never look at again.

At the time of writing, NTA hasn't released the official NEET UG 2027 syllabus. Aspirants preparing right now are expected to follow the latest NMC/NTA-prescribed syllabus and keep track of any official notifications or revisions as they come out closer to the exam. That said, the core structure of the syllabus rarely changes much year to year, so there's no reason to wait around before starting your preparation around it.

What the Syllabus Actually Covers

NEET draws almost entirely from NCERT Class 11 and Class 12 — Physics, Chemistry, and Biology, in roughly that order of difficulty for most students, though Biology carries by far the largest share of marks.

Subject	Resource
NEET Physics Syllabus	Chapter-wise details
NEET Chemistry Syllabus	Chapter-wise details
NEET Biology Syllabus	Chapter-wise details

Grab the official NEET syllabus PDF early if you haven't already. It sounds like a small thing, but having one reliable reference instead of piecing information together from five different sources saves a surprising amount of confusion later on.

Which Chapters Actually Carry the Weight

Here's something a lot of first-year droppers figure out too late: not every chapter is worth the same number of marks. NEET has leaned on certain chapters year after year, and previous paper trends make that pattern fairly visible.

In Biology, the heavier chapters are Human Physiology, Genetics & Evolution, Ecology, Cell Biology, Biotechnology, and Plant Physiology. Between them, these account for something like 45–50% of the entire Biology section. Given that Biology alone is worth 360 of the 720 total marks, that's not a section anyone can afford to under-prepare.

Chemistry leans on Chemical Bonding, Organic Chemistry, Coordination Compounds, Electrochemistry, and Mole Concept, making up roughly 35–40% of that section. Organic Chemistry specifically rewards students who sit down and actually work through reaction mechanisms on paper rather than reading them and assuming they'll remember.

Physics tends to draw most heavily from Modern Physics, Current Electricity, Optics, Electrostatics, and Mechanics — about 40–45% of the section. This is also usually the subject where students lose marks not from lack of knowledge, but from a question phrased in a way that hides a familiar concept behind unfamiliar wording.

None of these numbers are guarantees. They come from analysing how previous years' papers have played out, and NEET can always shift things around slightly. But as a starting point for where to spend your limited hours, this is about as reliable as it gets.

Turning This Into an Actual Plan

Knowing the weightage doesn't help much if it just sits in your notes. A few things worth doing with this information:

• Tackle the high-weightage chapters first in each subject, before spreading time thin across everything at once.
• Still cover the lower-weightage chapters eventually — NEET pulls at least a question or two from almost every chapter, and those add up over a 720-mark paper.
• For Biology specifically, go back to the NCERT text itself. A large chunk of Biology questions are lifted almost directly from textbook lines, so paraphrased notes alone won't cut it.
• Test yourself on a topic right after finishing it instead of waiting weeks. Waiting means relearning half of it later anyway.

Resources Worth Using Alongside the Syllabus

Having the syllabus mapped out is only half the job. The other half is actually working through it — revising, practicing, testing yourself — without losing track of what you've covered and what you haven't.

Physics Wallah has put together a set of resources that cover most of this together instead of forcing you to hunt for each piece separately:

Resource	What It's For
NEET Chapter-wise PYQs	Practicing questions tied to a specific chapter
NEET Mind Maps	Fast visual revision before exams
NEET MCQs	Regular practice across all three subjects
NEET Diagrams	Visual understanding, particularly useful in Biology
NEET Formula Sheets	Quick recall for Physics and Chemistry
NEET Sample Papers	Full-length practice under real exam conditions

Used together over the course of the year, these cover the full cycle — learn a concept, practice it, revise it, then test it under time pressure. That cycle, repeated consistently, tends to matter more than any single resource on its own.

FAQs

Q1. Has NTA released the official NEET 2027 syllabus?

Not as of now. Until it's officially released, students should continue following the latest NMC/NTA-prescribed syllabus and watch for updates as NTA announces them.

Q2. Which subject should get the most attention while studying?

Biology, simply because it carries 360 of the 720 total marks — more than Physics and Chemistry combined.

Q3. Which chapters matter most in each subject?

Human Physiology, Genetics & Evolution, and Ecology for Biology; Chemical Bonding and Organic Chemistry for Chemistry; Modern Physics and Current Electricity for Physics.

Q4. Can I skip chapters that carry lower weightage?

It's risky. Low-weightage chapters still contribute a question or two each, and across the full paper, that adds up to marks you don't want to give away.

Q5. How accurate is the chapter-wise weightage data?

It's built from analysing previous years' papers, so it's a solid guide, but the actual exam can shift slightly from year to year.

Q6. What other resources help besides knowing the syllabus?

Chapter-wise PYQs, mind maps, MCQs, diagrams, formula sheets, and sample papers each support a different stage of preparation — from first learning a topic to testing it under real exam conditions.
