The National Testing Agency (NTA) has officially released the NEET 2025 syllabus, and there’s a major update. ⬆️

Several topics have been removed ❌, some have been added ✅, and some have been deleted but still need to be studied. It’s crucial to be aware of these changes because they can impact your NEET score.

I know there’s a lot of confusion in your mind regarding the NEET 2025 syllabus changes.

But don’t worry! I’ve got you covered with a detailed subject-wise breakdown of the NEET deleted syllabus 2025.

Let’s dive in and see what’s changed! ⬇️

📘 NEET 2025 syllabus changes – Subject-wise breakdown

To reduce the burden on students, NTA has revised the NEET 2025 syllabus, removing certain topics from Class 11 & 12 NCERT books. This allows aspirants to focus on only the relevant topics for the exam.

But wait, there’s more! NTA has also introduced new topics to the syllabus, meaning you need to adapt your preparation strategy accordingly.

🧬 Biology deleted syllabus NEET 2025

Biology holds a major weightage in the NEET exam, so let’s start with it. As I mentioned earlier, NTA has removed some topics and chapters from the NEET syllabus. These topics are no longer included in the new NCERT books, meaning if you’re using old NCERTs, you can skip them. Many students continue using the same set of books even after syllabus changes. This can confuse you and make you study extra topics that are no longer needed. At this stage, it is important to use the best books for NEET preparation and stay aligned with them.
