Scoring 150+ in NEET Chemistry does not require memorising every reaction or spending hours solving the toughest numericals. What matters more is understanding how to prepare for Physical, Organic and Inorganic Chemistry differently.

Chemistry carries 180 marks through 45 questions. To cross 150, you need strong fundamentals, accurate question-solving and consistent revision. A focused combination of NCERT, PYQs, MCQs and regular tests can be more useful than collecting multiple books.

What Does 150+ in Chemistry Require?

A 150+ target means getting most questions right while keeping negative marking low.

If you are currently scoring 100–120, do not immediately increase your question count. Find the source of your mistakes first.

You may be losing marks because of:

• Calculation errors
• Forgotten reactions
• Weak concepts
• Poor revision
• Confusion between similar facts
• Spending too much time on difficult questions

Once you know the reason, you can change your preparation accordingly.

If you are using mock tests to understand where your marks are being lost, How to Identify Your Weak Chapters Through NEET Mock Tests can help you turn test performance into a more focused preparation plan.

Keep NCERT at the Centre

NCERT should be a regular part of your Chemistry preparation, particularly for Inorganic Chemistry and important portions of Organic Chemistry.

Read chapters carefully and notice definitions, reactions, properties, examples, exceptions, tables and specific statements.

Do not treat NCERT as a book to finish once. Return to it during revision and after solving questions. If a PYQ exposes a weak area, go back to the relevant section instead of simply memorising the answer.

Physical Chemistry: Understand Before You Calculate

Physical Chemistry becomes manageable when concepts and formulas are connected.

Before solving numericals, understand what a formula represents, what its variables mean and when it should be used. Start with basic problems and gradually move towards NEET-level questions.

Regular practice is essential because reading a solved numerical does not build the same skill as solving it yourself.

Maintain a short formula sheet containing important formulas, conditions and common calculation errors.

Whenever you make a numerical mistake, identify its cause. It could be the wrong formula, incorrect unit conversion, calculation error or misunderstanding of the question.

Organic Chemistry: Build the Logic

Organic Chemistry becomes difficult when every reaction is memorised as an isolated fact.

Begin with the fundamentals, especially General Organic Chemistry, reaction mechanisms and isomerism. These concepts help explain why different reactions occur.

When studying a reaction, focus on the starting compound, the change taking place, the product and the conditions involved.

Create reaction maps where useful so that connected reactions become easier to remember.

After studying a chapter, practise MCQs and PYQs. If you repeatedly forget a reaction, return to the original NCERT content and understand it again rather than memorising only the correct option.

Inorganic Chemistry: Revise NCERT Repeatedly

Inorganic Chemistry contains many facts that can disappear from memory if they are not revised regularly.

Read NCERT carefully and focus on trends, properties, compounds, reactions, examples and exceptions.

Active recall can make revision more effective. Close the book and try to reproduce important information before checking the text.

Do not assume that one detailed reading is enough. For a 150+ target, repeated exposure to NCERT can make a major difference.

For a broader view of which chapters deserve greater attention across all three subjects, you can also refer to the most important chapters for NEET Physics, Chemistry and Biology.

Give Each Branch a Different Strategy

One of the biggest preparation mistakes is treating all Chemistry chapters in the same way.

For Physical Chemistry, prioritise concepts and numerical practice.

For Organic Chemistry, strengthen fundamentals and understand reaction patterns.

For Inorganic Chemistry, focus heavily on NCERT reading and revision.

Your time should also reflect your weaknesses. If Physical Chemistry is already strong but Inorganic Chemistry is consistently reducing your score, additional Physical Chemistry practice may not be the best use of your time.

If your syllabus is incomplete, chapter selection becomes even more important. How to Prioritise Chapters When Your NEET Syllabus Is Incomplete can help you organise your preparation when you cannot cover everything at the same pace.

Use PYQs Throughout Preparation

Previous-year questions should be part of your preparation from the beginning.

After completing a chapter, solve its relevant PYQs. Look for recurring concepts and understand how familiar topics are converted into questions.

Do not learn PYQs as fixed answers. Use them to identify the NCERT concepts behind the questions.

This also helps you understand the level and style of questions you need to prepare for.

Take Chapter-Wise and Mixed Tests

Start with chapter-level tests while building your foundation. Once you have covered more of the syllabus, introduce mixed Chemistry tests.

Mixed practice is important because the actual examination requires you to move between Physical, Organic and Inorganic Chemistry.

After every test, analyse more than the final score.

Check which chapters caused problems, what type of mistakes you made and whether the issue was knowledge, confusion, calculation or carelessness.

Your test analysis should determine your next revision session.

You can also read How NEET Mock Papers Can Help Identify Weak Areas Before the Exam to understand what to look for beyond the final score.

How to Improve Accuracy

A 150+ target requires control over avoidable mistakes.

Read the complete question before selecting an option. Pay attention to words such as “incorrect,” “except,” “maximum” and “minimum.”

For numerical problems, check units and calculations. In Organic and Inorganic Chemistry, avoid selecting an answer simply because it looks familiar.

Improving these small habits can help reduce unnecessary negative marking.

If You Are Below 100

Start with the basics instead of jumping into advanced material.

Strengthen NCERT and identify the chapters responsible for most of your mistakes.

For Physical Chemistry, rebuild concepts and practise basic numericals. For Organic Chemistry, improve your fundamentals before memorising reactions. For Inorganic Chemistry, prioritise NCERT and repeated revision.

Increase question difficulty only after the foundation becomes stable.

If You Are Scoring 120–140

At this stage, you may already have a reasonable understanding of Chemistry. Your next improvement could come from eliminating smaller mistakes.

Review recent tests and identify recurring problems. You might be losing marks through calculations, forgotten facts, rushed reading or confusion between two options.

Work specifically on those areas rather than changing your entire strategy.

If the same mistakes continue appearing in your tests, keeping a dedicated mistake list can help. You can also refer to NEET Mistakes Every Aspirant Must Avoid to Improve Their Score while reviewing your preparation.

If You Are Already Above 150

Once you consistently cross 150, focus on maintaining accuracy.

Continue with NCERT revision, PYQs and mixed tests. Review incorrect and guessed questions regularly.

Avoid constantly adding new resources. At this level, strengthening existing knowledge is usually more useful than collecting more material.

How Many Books Do You Need?

You do not need a large Chemistry library.

Keep NCERT as your foundation and add practice material only where necessary. A useful numerical resource can support Physical Chemistry, while suitable question practice can strengthen Organic Chemistry.

For Inorganic Chemistry, additional books should not replace repeated NCERT revision.

The best resource is one you can complete, revise and use effectively.

For students comparing resources across subjects, Best Books for NEET Preparation 2027: Physics, Chemistry & Biology can be used as an additional reference.

A Simple Chemistry Preparation Cycle

Your preparation can follow a straightforward pattern:

Learn → Practise → Test → Analyse → Revise

Study a concept, solve questions, test yourself and identify mistakes. Then return to the weak areas and repeat the process.

As NEET approaches, gradually increase revision, PYQs and mixed tests.

For longer revision planning, you can use the 30-day, 60-day and 90-day NEET revision strategy to structure your revision according to the time available.

Conclusion

A 150+ score in NEET Chemistry is built through accuracy and consistency rather than an unnecessarily complicated study plan.

Use different strategies for the three branches. Understand Physical Chemistry before solving numericals, build reaction logic in Organic Chemistry and repeatedly revise NCERT for Inorganic Chemistry.

Keep PYQs and tests in your routine, analyse every mistake and avoid collecting resources simply for the sake of studying more.

Understand the concept. Practise the question. Find the mistake. Revise it. Repeat.

That focused approach can help turn Chemistry from a difficult subject into a reliable scoring opportunity in NEET.
