    Physics Last Minute Preparation Tips

    JEE Main Physics Last Minute Preparation

    • Focus on Strong Points, Don't Start Anything New: Rely on your strong points and ensure no question from these areas is left or is incorrect. Last minute is not the time to strat anything new. Hone and sharpen strongholds.
    • Revise important formula: Take reference of short notes and flash cards created to revise formulas and tricks. This is not appropriate time to go through details in the books. Revise those topics that carry weightage and have dominant question papers of last few years.
    • Go easy with the mock test: Certain students get affected by the hype of solving practice papers and spend too much of time on that. Where mock testvare essential just blindly practicing them will bore no fruit. It is important to solve one to two mock test each day, analyse them and work on the weak points. This ensures that mistakes made are not repeated on the exam day. A bad nock test should not demoralise candidate rather than help in improvising.
    • There is no room for self doubt: Any bad practice seasion or mock test or peer pressure should not demotivate you. Last few days are crucial so keep youself mentally strong. Revise topic wise, practice questions based on that and move on to the next topic without any doubt.
    • Take timely breaks: Continuous study can cause fatigue, thus it is advised to take small breaks after every hour or so to break the monotony and keep the momentum high. Though the breaks can be timely and as per schedule to ensure there is no wastage of time.
    • Eat healthy and taje good sleep: Depriving yourself of sleep in the last few days can cause high stress level and lack of concentration. Thus ensure good amount of sleep and relaxation. East healthy, avoid junk and try to keep fit especially in the last few days before the actual exam.
    • Avoid Preparation Discussion: Overdiscussing preparation kevel with friends and family can increase anxiety amount aspirants. This is a common tendency among aspirants hence

    Ideal way to Score 100+ in JEE Main Physics section

    • Practice Previous Year Question Paper: Solving previous year question paper will give an idea on what ki d of questions are asked and in which domain you lack. Enhance your score by practicing varied number of questions.
    • Shortcuts and formulae: To ace numerical type of questions formulas play an important role. Mugging up formulas will help arrive at the solutions quickly. If effort is taken to understand them, formulas can be derived on own.
    • Time Management: Students should not spend more than 45-50 minutes in physics as 30-40 % questions are theiritical in nature, thus can be attempted in less than a minute And as they say every second saved is every second earned.
    • Elimination of Wrong Answers: At the first instance elimination of options that seem incorrect by intelligent guessing and wisdom can lead to solve questions the right way and even arrive at correct answer.
    • Easy question first: It is advised to solve easy questions first and questions that seem approachable. This will maximise the number of questions attempted and score good marks. Time leaft can be spent on questions that are remaining.

    It is important to note that the preparation strategies for NEET Physics and JEE Physics differ considerably. NEET Physics expectations are not as high as those of JEE Physics because it is an entrance exam to medical colleges while JEE is for engineering colleges. 

    1. While preparing for NEET Physics, one must not refer to books of JEE Physics because NEET does not require you to solve the complex numerical asked in JEE Advanced. This is also because NEET aspirants usually opt out of Mathematics after Class 10 while JEE aspirants have a strong relationship with Mathematics. 

    2. The exam pattern of NEET Physics and JEE Physics differs considerably. Therefore, preparation strategies must be formed accordingly. 

    3. NEET Physics asks only MCQs while JEE Physics asks MCQs and numerical. Practice should be done keeping this in mind. 

    4. NEET Physics preparation must be lighter than JEE Physics preparation due to the nature of the difficulty of questions. JEE Physics requires more intense practice with complex numerical.

    Tricks to Solve Physics Questions

    Tricks to Solve JEE Main Physics Questions

    • If you already have notes from the teacher of your coaching institute, then there is no need to make comprehensive notes again.
    • You may enhance the class notes by using a red pen or neon highlighter to illustrate important concepts.
    • You can also add to the notes some good/popular questions that you answered earlier so that you will certainly see them again when revising your notes.
    • You can add tips/tricks in the space provided for margins to prevent any errors that you might have learned later. 
    • You can make short notes with full-length notes too, but that will take a lot of time.
    • Do not waste time writing down notes again and again. 
    • Develop an interest in the concepts and formulas that you are studying. A lack of interest will make it harder to remember formulas.
    • Use visual memory to connect concepts to formulas. This helps in easy memorization because you will know the process behind the formulas. 
    • Practice the formulas you want to memorize as often as you can. The more you practice, the better you will understand the application of formulas. 
    • Writing down formulas again and again will help in speedy and long-lasting memorization. 
    • You can stick the written formulas on the wall so that you will repeatedly see them. 
    • Before you go to sleep, think about the formulas. Your brain will have better chances of remembering them the next day. 

    Tips for JEE Main Physics During the Exam

    • Find the easier and approachable questions first aand solve them
    • Keep on solving questions and fill OMR sheet side but side
    • Do not opt for guess work it can degrade your marks and overall score.
    • Do not panic if stuck at any questions, try to be calm and solve the maximum you can.
    • Do not assume that you have full one hour for physics section, try to wrap up the portion in 45 minutes or so. the remaining time is neccesary for revision and omr sheet filling.
