    NTA has also cleared the rumours of changes in the syllabus by releasing an official notice. The syllabus is still the same as it is mentioned in the official brochure. 

    • NEET chemistry syllabus is divided into various subsections which require thorough preparation. However, most of the candidates find chemistry to be an easy and scoring subject. 

    • In NEET 2020, a total of 45 questions will be asked from chemistry. All candidates are advised to go through the exam pattern. Check NEET Exam Pattern

    To help candidates in their preparations, we are providing the unit wise detailed syllabus of chemistry for both class XI and XII. Along with the syllabus, we have also provided the weightage of questions, the difficulty level of questions, and much more. Candidates are advised to read the article to get a better understanding of NEET chemistry syllabus.

    Preparation Tips for NEET 2020 Chemistry Paper

    Preparation Tips for NEET 2020 Chemistry Paper

    If we go through the paper analysis of previous year NEET chemistry paper then most of the test takers rated the subject to be easy in terms of difficulty. If a candidates is well prepared for all the 3 sections i.e. Organic, Inorganic, and Physical section of chemistry then he/she can score very well in this section. Here are some of the preparation tips for candidates who planning to appear for NEET 2020:

    Tip 1: Practice Papers and Mock Tests:

    • With the help of practice papers or mock tests you can work on the speed and accuracy of answering the questions. 
    • Candidates are advised to focus on accuracy first and then on speed. 
    • By taking mock tests you can judge your performance level and work on your weaker areas or topics. 

    Direct Link for NEET Mock Test by NTA

    Tip 2: Preparing Notes for Revision:

    • Candidates should prepare handwritten notes for revision. 
    • Revision will help you in memorizing the topics for a longer period of time. 
    • You must note down all the important formulas, facts etc and revise them daily. 

    Tip 3: Managing your Time:

    • Prepare a proper plan or time table and only follow that plan. Do not come under peer pressure and focus on your preparations. 
    • Your time table should include frequent breaks so that you can relax your body and mind. 
    • Set some monthly or weekly goals so that you can complete your syllabus on time. For example, you can divide 8 topics into 2 topics a week. But in order to achieve these goals you have to stick to your time table. 

    Tip 4: Divide syllabus based on Difficulty Level:

    Candidates can divide the sections or topics for preparation based on the difficulty level or number of questions asked from that particular section. 

    • High Priority Topics - Around 20 to 25 questions can be asked from these topics: General Organic Chemistry, Hydrocarbons, Alcohol, Aldehyde, Amines, Periodic Table, Metallurgy, Hydrogen, s, p, d, f-block, Surface Chemistry. 
    • Medium Importance - Around 10 to 15 questions can be asked from these topics: Chemistry in everyday life, Environmental chemistry, Polymers, Some basic concepts, Solid states, Coordination. 
    • A Few Questions - Around 1 to 5 questions can be asked from these topics: Thermodynamics, Chemical kinetics, Equilibrium, States of matter, Electrochemistry, Solution.
