NEET UG is one of the most important exams for students who aspire to become doctors. Among the three subjects, Chemistry plays a crucial role in boosting the overall score.
With 45 questions carrying 180 marks, Chemistry offers strong scoring potential when prepared in the right way. Unlike Physics or Maths, it involves more concepts to remember, which gives you a good opportunity to score well.
On this page, we’ll discuss the most important chapters when it comes to Chemistry, and also give you some tips on improvement in Chemistry.
NEET 2026 Chemistry Exam Pattern & Weightage Distribution
But before we get into the chemistry important chapters for NEET, we need to understand the NEET exam pattern and weightage distribution for NEET UG.
| Category | Details |
| Total Chemistry Questions | 45 |
| Section A | 35 questions (compulsory) |
| Section B | 10 questions (attempt any 5) |
| Marks per Question | +4 correct, −1 incorrect |
| Total Chemistry Marks | 180 |

How to Prepare for NEET Chemistry Perfectly
Now that you understand the most important chapters for NEET Chemistry, you must be aware of proven strategies that have worked to make the preparation of Chemistry far easier than it is for some students. We at Aakash regularly employ these strategies with our students, and as a result, we get so many NEET toppers. Now, let’s learn the strategies one by one.
Focus on NCERT First
Make sure you master the NCERTs properly, as many questions are directly asked from them, and as a result, it is important to keep them handy. Be sure to read every line carefully and underline definitions, reactions, and examples.
Focus on Conceptual Clarity
When studying for Physical Chemistry, do not just memorise things; make sure you understand how they work. Do problems that use formulas on a regular basis. You will benefit from revising the basic arithmetic concepts like logarithms and mole calculations.
Practice Previous Year Papers and Mock Tests
One good approach to practice is through the NEET previous papers. Students can see which chapters repeat more by doing NEET Chemistry chapter-wise weightage 2025 papers. Neet Mock tests also help you get faster and more accurate.
- Answer at least 10 to 15 years’ worth of NEET Chemistry PYQs.
- Look at your mistakes and work on your weak spots.
- Take practice examinations with a timer to boost your confidence.
Memorise Inorganic Chemistry with Smart Tricks
There are a lot of facts, trends, and properties in inorganic chemistry. It might seem boring, but it provides you with direct questions in NEET. Chapters like p-Block, d-Block, and Coordination Compounds are very important for NEET chemistry. Use the right strategies, including employing tables to help you remember the NCERT.
Conclusion
So there you have it, now you know the most important Chemistry chapters for NEET and the strategies you can use to prepare for them. If you’re looking for some more clarity, you can use some Neet mock tests to test where you currently stand, identify your weak points and work on them.
FAQs
Q1. How can I prepare for Organic Chemistry for NEET?
