NEET Chemistry 2021 – Important Topics and Preparation Tips

NEET Chemistry is divided into three sections, namely, Physical, Organic and Inorganic Chemistry. Compared to Biology and Physics, Chemistry is considered to be the most scoring section. If prepared thoroughly, chemistry can help students to secure a meritorious position in the exam. Out of a total 720 marks (180 questions), NEET Chemistry comprises 180 marks (45 Questions). Therefore, it is essential for students to prepare well for the Chemistry section.

Nearly 36% of weightage in NEET Chemistry section is allotted to Physical and Inorganic Chemistry while 28% of weightage is allotted to Organic Chemistry Syllabus as per previous trends, in some instances, equal marks-distribution is seen between all three sections. In order to enhance your chemistry preparation, it’s crucial to have thorough planning considering all your strengths, weaknesses and time availability for exam preparation.

NEET concepts:

NEET Physical Chemistry

It’s the numerical section of the NEET Chemistry paper. Understanding the concepts is crucial for Physical Chemistry. It’s difficult to interpret a numerical without understanding the related concepts. Students are advised to have a strong grip on all the concepts taught in NCERT textbooks. Also, maintain a list of important formulas and practice questions regularly. From this section, the probability of getting theory-based questions is quite less. However, with regular practice, you can score good marks in this section.

Organic Chemistry for NEET

Students are advised to understand and memorize all the equations, formulae, and reactions given in NCERT textbooks. Memorize the names of various compounds that constitute reagents, subtracts, etc. To gain command over this section, practice a variety of questions from reference books as well.

Inorganic Chemistry for NEET

It is the easiest section of NEET Chemistry. Most of the students complete this section in very less time as numerical and formula-based questions are usually not asked from this section. Students are advised to understand the basic concepts taught in NCERT textbooks thoroughly.

NEET Chemistry Preparation Tips:

Formulate a proper Preparation Strategy: Planning plays a crucial role while preparing for a highly competitive exam like NEET. Instead of having a long-term goal, create small and achievable goals. This will allow you to monitor your progress more clearly. Prepare a weekly study plan and target certain topics each week. Focus on your target and work hard to achieve it within the specified time frame.

Refer NCERT Textbooks: Several times the questions asked in the NEET exam are picked directly from the concepts taught in NCERT textbooks. Therefore, the students are advised to cover all the concepts taught in NCERT textbooks before moving to other reference books. The language used to explain concepts in NCERT textbooks is simple and easy to understand. Once you are completely done with NCERT textbooks you can follow the given below reference books to enhance your NEET preparation.

Name of Book Author
Inorganic Chemistry J.D. Lee
Physical Chemistry O.P. Tandon
Organic Chemistry M.S. Chouhan

Practice previous years’ question papers: Solving previous years’ question papers is one of the best ways to prepare for a competitive exam like NEET. It helps to evaluate your preparation level, helps in quick revision of syllabus, makes you familiar with the examination pattern, and improves your speed and time management skills crucial for successfully completing the exam.

The students are advised to incorporate the above-mentioned preparation tips into their routine so that all the topics included in NEET Chemistry syllabus can be covered smoothly. The students can analyse the topic wise marks distribution of different concepts and plan their preparations accordingly.
