Introduction
NEET Chemistry is often considered the deciding factor for students aiming for a top rank. It acts as a bridge between the memory-based Biology and numerically heavy Physics sections. With 45 questions carrying a total of 180 marks, scoring 150+ in Chemistry can greatly enhance your overall score and rank. Chemistry not only provides a balance to the exam but is also the section where consistent preparation and revision can help secure a significant number of marks without ambiguity.
The key to cracking Chemistry in NEET is to develop a smart strategy rather than aimlessly covering too many resources. In this blog, Deeksha Vedantu outlines how you can target the most important chapters, master NCERT, and practice effectively to confidently aim for a 150+ score. You will find a breakdown of NEET Chemistry by topic, key focus areas, how to revise, and tips on avoiding common mistakes.
Understanding the NEET Chemistry Blueprint
Physical, Organic, and Inorganic Chemistry
NEET Chemistry is divided into three sub-sections:
- Physical Chemistry: Numericals, formulas, concept-based questions that require practice and understanding of logic
- Organic Chemistry: Reactions, mechanisms, conversions, and functional groups that depend on conceptual clarity and recall
- Inorganic Chemistry: Facts, trends, and direct theory from NCERT which are more memory-based and fact-driven
Understanding the nature of each branch helps in designing a preparation plan that gives proper attention to both conceptual understanding and memorization.
Weightage and Trends from Previous Years
NEET Chemistry Topic-Wise Weightage
| Section | No. of Questions (Approx.) | Marks |
| Physical Chemistry | 12-14 | 48-56 |
| Organic Chemistry | 14-16 | 56-64 |
| Inorganic Chemistry | 15-17 | 60-68 |
The balance is fairly distributed across the three branches, making it important to maintain a uniform preparation strategy. NEET does not tend to favor one section over the other, and trends show repetition of key concepts from each branch.
Class 11 vs Class 12 Chemistry: What to Prioritize
- Class 11: Atomic Structure, Chemical Bonding, Thermodynamics, GOC, Redox Reactions, Equilibrium, States of Matter
- Class 12: Coordination Compounds, Electrochemistry, Aldehydes & Ketones, Biomolecules, Surface Chemistry, Haloalkanes & Haloarenes
Both years are equally important, and about 22-23 questions come from each. Class 11 builds the conceptual base, while Class 12 is more focused on applied and reaction-based learning.
High-Scoring Topics in NEET Chemistry
Physical Chemistry
Physical Chemistry is logical and numerical. Once you grasp the concepts, it becomes predictable and high-scoring.

Inorganic Chemistry
Inorganic Chemistry requires mastery of NCERT. Questions are direct and fact-based.
- Periodic Table and Properties: Trends in metallic character, size, ionization potential
- Chemical Bonding: Hybridization, dipole moment, resonance, molecular geometry
- Coordination Compounds: Ligands, coordination number, nomenclature, CFT application
- p-block Elements: Structures of oxides and halides, acidic/basic nature, trends
- s-block and Hydrogen: Reactivity trends, anomalous properties of Li, reactions of H2O2
Strategy to Score 150+ in NEET Chemistry
Build Conceptual Understanding First
Make sure you know the “why” behind every concept. Physical Chemistry especially demands clarity in topics like enthalpy, entropy, and equilibrium. Instead of memorizing, focus on understanding the derivation and logic behind each formula and concept. Use visualizations like energy level diagrams or thermodynamic graphs to strengthen your grasp. Watch video lectures or animations to better understand abstract topics like bond enthalpy or free energy changes.
Focused Practice on NCERT-Based Questions
Underline and revise NCERT content multiple times. Highlight facts and create side-notes for quick recall. For every chapter, list out the important in-text examples and end-of-chapter exercises and practice them until perfect. Use Deeksha Vedantu worksheets for chapter-wise NEET questions based on NCERT lines. These help simulate the kind of questions that appear in the exam and train you to think in the NCERT way.
Weekly Topic-Wise Tests and Error Review
Set up a weekly revision timetable. After each topic, attempt 25-30 MCQs and analyze errors. Identify whether the mistake was due to a lack of conceptual clarity, silly mistakes, or misreading the question. Create a three-column error log with the question, your mistake, and the correct concept for future review. Revisit this log before every test to avoid repeating the same errors.
Strengthen Weak Areas Using Flashcards and Formulas
Use color-coded flashcards. Green for reactions, blue for formulas, yellow for concepts. Carry them during travel or short breaks to reinforce passive learning. Write the concept or reaction on one side and its application or mechanism on the other. Use apps like Anki for digital flashcard creation and spaced repetition. Include exception-based facts that are often tested in NEET.
Solve Previous Year Papers Religiously
Create a PYQ tracker. Mark every question you got wrong and review that concept weekly. Categorize PYQs by topic and solve them multiple times. Track patterns—notice which types of questions are frequently repeated and which concepts often appear in assertion-reason formats. Use mock exams that mix PYQs with predicted questions for a complete assessment.
Use Formula Sheets for Physical Chemistry
Keep laminated formula cards for Thermodynamics, Electrochemistry, and Kinetics. Revisit them daily. Add side notes with units, conditions, and common mistakes next to each formula. Use sticky notes in your textbook or notebook to flag the most-used formulas. Quiz yourself weekly using these sheets. Include solved examples using the formula to understand real-world application.
Mix and Match Revision Method
Don’t study all chapters from one section back-to-back. Alternate between Physical, Organic, and Inorganic to stay engaged and retain better. For example, pair a calculation-heavy chapter like Electrochemistry with a memory-based chapter like p-block elements. This reduces fatigue and helps maintain focus. Design a balanced schedule that ensures each subject type is revised twice every 10 days. Mix theoretical revision with active problem-solving to maximize retention.

Common Mistakes to Avoid
- Ignoring NCERT for Inorganic: Almost all Inorganic questions come from NCERT
- Over-reliance on reference books: Avoid too many sources; stick to one primary and one secondary book only
- Neglecting numerical practice in Physical Chemistry: Without solving, you won’t improve speed or confidence
- Last-minute cramming of reaction mechanisms: Instead, understand functional group behavior and predict products logically
- Not taking mock tests seriously: Mock tests simulate real exam pressure and help in time management
- Skipping conceptual clarity in GOC: Misconceptions in GOC can lead to errors across multiple Organic chapters
