    Tips to Make Notes

    Following are a few tips on how to make your revision notes for JEE Main 2022:

    Prepare your notes

    • It is not recommended that JEE Main aspirants copy or borrow notes. Notes can be made in any way that suits one’s needs and understanding.
    • Preparing study notes might also help you comprehend the material better.
    • Prepare JEE Main study notes on loose papers if at all possible.
    • Assemble these stray documents into a file in an orderly fashion.
    • This method of taking notes aids in effective exam preparation.

    Keep everything close at hand

    • Prepare JEE Main study notes on loose papers if at all possible.
    • Assemble these stray documents into a file in an orderly fashion.
    • This method of taking notes aids in effective exam preparation.

    When you’re reading for the first time, don’t take any notes

    • Making notes after the initial reading frequently results in a mess, with nearly the entire chapter highlighted.
    • Aspirants should solely concentrate on learning the ideas after the first reading.
    • After the second or third reading, make some notes.

    The most important points should be highlighted

    • This is based on a person’s understanding and preference.
    • To mark points, use a variety of coloured highlighters.
    • You can colour code concepts in yellow and key formulas in red.

    Use Post-It Notes

    • The JEE Main syllabus is extensive and takes time to finish.
    • There can be significant gaps between visits to the same chapter, making learning more challenging.
    • Sticky notes are very handy in these situations.
    • Jot down crucial facts on these notes and tape them to the corner of relevant pages for easy memory.

     Make a list of your errors as well

    • There are frequently challenging problems when tackling JEE Main Mock Tests and Previous Year Papers.
    • Aspirants for JEE Main should keep track of such questions in their notebooks.
    • Go over these questions again before taking the JEE Main 2022 exam.

     Aspirants for JEE Main 2022 can watch free video lectures

    • Since last year, NTA has offered free content-based video lectures on their official website.
    • Experts from IIT create these video lectures.
    • These lectures assist applicants in preparing for the graduate-level engineering test, particularly those who cannot afford to attend coaching institutes.
    • These videos can help you learn and revise for the JEE Main 2022 exam.

    Examples of JEE Main 2022 Physics Important Questions 

    Question: The picture of an object created by a plano-convex lens at an 8-metre distance behind the lens is actually one-third the size of the item. The light inside the lens has a wavelength that is 2/3 that of light in open space. The lens’s curved surface has a radius of

    1. 3m
    2. 10m
    3. 7m 
    4. 9m

    Answer: Given that- positive of image, v = +8

                                      magnification, m = 1/3

     m = v/u = 1/3

            8/u = 1/3 

            u = 8 * 3

            u = -24

    μ = λ air / λ medium

    λ air = 1 and λ medium = ⅔

    So, μ = 3/2

    According to the lens formula, 1/f = 1/v + 1/u 

    where , 1/f = (u – 1) (1/R – 1/∞)

    Substituting all the values we get R = 3m. Therefore the correct answer is (a) R = 3m.

    Question: A wire’s resistance at 20°C room temperature is found to be 20W. Now, in order to increase the resistance by 20%, the wire must be heated to?

    [The temperature coefficient of resistance of the wire material is 0.002 per °C].

    (a) 176°C                 

    (b) 124°C                

    (c) 142°C                 

    (d) 133°C

    Answer: R1 = R0 (1 + αt)

    At the beginning R0 (1 + 20α) = 20Ω

    Finally, R0 (1 + αt) = 24 

    At the beginning R0 (1 + 20α) = 20Ω

    Finally, R0 (1 + αt) = 24

    Now, 6/5 = (1 + αt) / (1 + 20α) 

    Substituting all the values we get: 

    5 + (5 x 0.002 x t) = 6 + 120 x 0.002

    0.01t = 1.24

    t = 1.24/0.01 = 124°C 

    Hence, (b)b) 124°C is the correct answer. 

     

    1. On the Celsius scale, the absolute zero temperature is

            0∘C

    1. 32∘C
    2. 100∘C
    3. 273.15∘C

    Answer: 

    T = 273.15+t∘C 

    ⇒ 0 =273.15+t∘C

    ⇒ t =−273.15∘C

    Hence, the correct answer is (d) 273.15∘C

    1. The volume of a gas becomes four times if 
    1. Temperature becomes four times at constant pressure
    2. Temperature becomes one fourth at constant pressure
    3. Temperature becomes two times at constant pressure
    4. Temperature becomes half at constant pressure

    Answer:

    V∝T (as constant pressure)

    Hence, the correct answer is (a) Temperature becomes four times at constant pressure.

    Last-minute preparation tips

    • Solving Previous Years’ Papers: Students should solve JEE papers starting in 2012 to gain a better understanding of the newest trends [since the JEE pattern has changed dramatically since the introduction of JEE(M) and JEE(Adv)] and the level of difficulty of the entrance exam. Before taking the entrance exam, students should complete at least 15-20 practice papers. Solving such exams in a timed manner helps you gain time management skills, which will improve your exam performance. Students can access the previous 14 years’ question papers on the Aakash website and detailed solutions. 
    • Relaxed Mind: Before taking the exam, students are recommended to relax and have some fun or listen to music to relieve any fears or tensions they may have. A good night’s sleep and a clear mind are essential for getting the most out of your abilities.
    • Have Faith in Yourself: The biggest thing you can do when taking JEE is to have faith in yourself. It would help if you were confident in passing the exam with a good score after all of your studying, preparation, and practice. Self-confidence allows you to win half of the battle. Going in with the intention of winning is a good idea. This unshakeable faith will undoubtedly result in success.

    Conclusion

    Preparing thoroughly while there is still time will provide you with an advantage for the upcoming JEE 2022 exam, such as

    • You’ll be well-prepared when the big day arrives.
    • After you’ve completed half your preparations, you’ll have plenty of time to revise and prepare for the remaining half of the syllabus.
    • You’ll get a sense of how the actual exam will be structured and how difficult it will be.
    • You’ll have plenty of time to discover your weaknesses and turn them into assets.

    3. How can I choose the best JEE Physics study resources to boost my score?

    While there are a variety of study resources available, selecting the best Physics material is crucial. Candidates should always use study materials that are formatted to match the exam. Students must use relevant books that provide clear explanations of topics and JEE-based exercises because time is crucial in JEE Physics preparation. They will be able to study more effectively as a result.

    4. In the JEE Physics reference books, which topic should I start with?

    Begin with the simpler JEE Physics concepts; these will increase your confidence and help you achieve a high score.

    • Modern Physics 
    • Currently Electricity
    • Laws of Motion 
    • Sound and oscillations
    • Thermodynamics and heat

    5. What are the best tips to study for the JEE Physics examination 2022?

    1. The following are some JEE Main 2022 Physics Preparation Tips:
    • Create a study timetable. 
    • Know your course material.
    • Set aside time to prepare for important topics.

    Is it your dream to study at an IIT? Then make sure you go through the JEE Main and Advanced eligibility criteria before sitting for the exam. 

    6. How crucial is the 11th-grade curriculum to improve your JEE Physics score?

    For the JEE Physics Examination, the class 11th curriculum is just as important as the 12th syllabus. Because the format and exact weighting of class 11th topics in the JEE Physics Examination changes every year, it is impossible to predict. As a result, treating it as equally important is preferable. 

    The NCERT Solutions for Class 11 Physics will help build a strong foundation for competitive exams and score high on school board exams. 

    Here are a few best books for JEE Main Physics: 

    Name of the book and author Features of the book
    Concepts of Physics (Vol. 1 and 2) by H.C Verma Quality problems on all topics
    Fundamentals of Physics by Halliday, Resnick & walker Concepts of all the topics
    Understanding Physics by D C Pandey (Arihant Publications): Set of books for

    • Electricity & Magnetism
    • Mechanics (Vol. 1 & 2)
