NEET preparation requires a thorough understanding of the syllabus, which is primarily based on the NCERT curriculum for Classes 11 and 12. NCERT had released a new edition of the Physics, Chemistry and Biology textbooks (printed in 2023) with the rationalised syllabus. As the NEET exam is based on the topics mentioned in NCERT, the NEET 2025 exam was expected to be based on this new rationalised NCERT syllabus.
As per the new rationalised syllabus for class 11 and 12, NCERT has deleted quite a few chapters in whole and in some other chapters, some of the topics have been deleted. Interestingly, the Prelims to each of the books state that the NCERT syllabus had been rationalised during COVID and in line with the aim to reduce load on the students as per the New Education Policy (NEP).
Of late, National Medical Commission (NMC) has released the Syllabus for NEET UG 2025 vide notofication no. U-14023/19/2023-UGMEB dated 6th October 2023, where NEET rationalised syllabus is not accepted completely by the NMC. You can check the NEET UG exam 2025 syllabus at the official website of the National Medical Commission.
Reduction or rationalization of NCERT Syllabus

Revised Updated NMC Syllabus for NEET UG 2025
The updated or reduced NEET syllabus as per NMC is not exactly as per the latest editions of NCERT books or the NCERT rationalised syllabus. In some places, some topics have been restored as per the earlier editions of NCERT.
A few topics have also been inserted which have hitherto not been part of NCERT books. At the same time, it’s very important to bear in mind that simply not mentioning a particular topic or sub-topic may not necessarily mean deletion.
Some of the topics omitted in the NMC syllabus for NEET may have a direct or indirect bearing on your problem-solving abilities and accuracy in the questions from the remaining chapters. So, you need to be extra cautious about your decision to completely omit the chapters or topics or limit your study to a certain level.
This would be the first time NMC has prepared the syllabus and it’s quite likely the paper setting is done by NMC or under the directions of NMC. So, each one of you must be mentally prepared for the surprises the NEET 2025 paper may throw up.
Prepare NCERT Rationalised Syllabus for NEET 2025 exam
Preparing for NEET 2025 with a focus on the NCERT Rationalised Syllabus requires a strategic approach, especially when the time available ranges from 1 to 4 months. Understanding the nuances of the rationalised syllabus and aligning your study plan accordingly is crucial.
How to prepare for NEET in 4 Months: With four months at your disposal, start by dissecting the NCERT Rationalised Syllabus. Identify the core areas and lay out a structured study plan, dedicating time slots for each subject – Physics, Chemistry, and Biology. Focus initially on building a strong conceptual foundation from the NCERT textbooks, as they are pivotal for NEET. Follow this up with problem-solving exercises and mock tests to gauge your understanding and application of concepts.
How to study for NEET in 3 Months: When preparing for NEET in three months, your approach should be more intensive. Allocate specific weeks to thoroughly revise each subject according to the rationalised syllabus. Incorporate a mix of learning methods – from reading NCERT textbooks to solving previous years’ papers. This period should be about reinforcing concepts and increasing familiarity with the exam pattern. Regular mock tests will help fine-tune your time management and accuracy.
Prepare for NEET in 2 Months: With two months left, shift your focus predominantly towards revision. Create a revision schedule that covers all the chapters as per the rationalised syllabus, placing extra emphasis on those with higher weightage. Utilize various revision tools like mind maps, flashcards, and summary notes for efficient learning. Regular practice tests are crucial at this stage to consolidate your learning and improve your speed.
Prepare for NEET in 1 Month: In the final month, prioritize revising and re-revising the NCERT content, as it forms the backbone of the NEET syllabus. Your study sessions should be interspersed with solving as many practice questions and full-length mock tests as possible. This is not the time for learning new topics but for mastering what you have already studied.
Regardless of the time frame, adapting your preparation strategy to align with the NCERT Rationalised Syllabus is key. Stay updated with any syllabus changes, and remember, consistent revision and practice are your best tools for success in NEET 2025.

Frequently asked Questions on NCERT Rationalised Syllabus for NEET 2025
Rationalisation appears too heavy a word and it could mean that some topics or chapters might be added as well in the process of rationalization. But there’s a sense of relief for you. In the name of rationalization, some chapters and some topics or sub-topics have only been removed.
Largely, NEET reduced syllabus by NMC is the same as NCERT rationalised syllabus. Primarily, except p-block, the chapters that had been omitted in the NCERT new books have been excluded in the NMC NEET syllabus. However, some topics in Biology have been freshly added too.
You can get the rationalised syllabus at the official website of NCERT at https://ncert.nic.in/rationalised-content.php.
In the Prelims to the rationalised books on its website, NCERT has stated as below:
In view of the COVID-19 pandemic, it is imperative to reduce content load on students. The National Education Policy 2020, also emphasises reducing the content load and providing opportunities for experiential learning with creative mindset. In this background, the NCERT has undertaken the exercise to rationalise the textbooks across all classes. Learning Outcomes already developed by the NCERT across classes have been taken into consideration in this exercise.
Contents of the textbooks have been rationalised in view of the following:
– Overlapping with similar content included in other subject areas in the same class
– Similar content included in the lower or higher class in the same subject
– Difficulty level
– Content, which is easily accessible to students without much interventions from teachers and can be learned by children through self-learning or peer-learning
– Content, which is irrelevant in the present context
