    JEE Main Chemistry Last Minute Preparation Tips

    • Make revison or short notes for last minute preparation along with flashcards for equtions and formulas.
    • Reise on a weekly or daily basis dividing the time equally to physical, organic and inorganic chemistry. 
    • Usually conceptual questions dominate JEE Main Chemistry question paper, so while revising remember not toindulge in core numerical problems and focus on concepts.
    • Make NCERT an exemplar book for Chemistry preparation in JEE Main especially for inorganic chemistry. 
    • Practice Organic as much as you can along  with clarity in theoritical concepts.
    • Revise exclusive topics in Chemistry like environmental chemistry and biolomecules.
    • Dont be tensed in the last moments-remember that that every question holds +4 marks and every incorrect response holds -1. So if even 2 questions are incorrect ypu will loose 10 marks in total which will lower your rank by 2000.
    • Cover up easy topics in physical chemistry first to boost confidence like redox reaction, electrochemistry, solid state, chemical kinetocs etc.
    • Revise periodic table on a daily basis as it is somewhat difficult to retain.
    • Lastly stay calm, get good sleep and eat healthy, overstressing can lead to unnecessary pressure and bad performance.

    Right Way to Score 100+ in JEE Main Chemistry

    Focus on the Right Study Material

    As they say less is more so do not spend unnecessary time on books that seem too difficult or not relevant to JEE. Hence there is no need to master Atkins Physical chemistry by heart, read a couple of books repeatedly rather than 5 books once.

    • Initiate with NCERT and keep one reference book for each section.
    • For inorganic chemistry NCERT + Past year question bank are enough
    • For organic chemistry the fat book by Wiley's Solomon is enough.

    Understand the Mole Concept

    Several students ignore the mole concept and give up easily. Though the topic plays a crucial role in physical chemistry. Get pro with it and solve the questions easily.

    Practice and Retain Daily

    Candidates who score high in chemistry have good retaining capability. And retention comes with regular practice. Chemistry questions in JEE Main are seem to be repeated with change in numerical values. Make a habit of solving at least 50 objective type questions daily.

    Mange Time During the Exam

    Spend the least amount of time possible in the chemistry section. Time should not be divided equally in 1 hour for each section. Try to wrap up chemistry section in less than 40 minutes, the additional time can be utilised in revision or solving lengthy ,mathematics questions. 

    Eliminate and Answer in Organic/Inorganic Chemistry

    Before ticking an option and arriving at a conclusion use the trick to eliminate an answer. This can especially be helpful in organic and inorganic chemistry. Eliminate a few answer and then answer.

    Approximations in Physical Chemistry

    JEE Chemistry section is not designed to test a candidate's mathematical or calculation skills. Thus smart play is important. So unless the options are too close to each other use the closest answer. This will help save time and increase speed.

    Attempt Chemistry Section First

    It is highly advisable by JEE Main toppers and experts to solve chemistry section initially before maths and physics. As chemistry is deemed to be less time consuming and easy it can be wrapped up easily. If mathematics or physics is picked up first it consumes a lot of time and at the end chemistry is compromised.
