You need to know your syllabus and understand the exam pattern. Make a plan and stick to it. Make a note of the books to refer from and practise as many mock tests or sample papers as you can.

Divide the syllabus into Class 11 and Class 12 and the topics as "Need to Learn", "Weak" and "Strong". Now it is important to check the weightage of each topic. In Physics, Modern Physics take the top slot with 5 questions. Heat and Thermodynamics, Optics, Current Electricity, Elcetrostatics get 3 questions each. Magnetic has 2 questions and the rest get 1 question each. In Chemistry, Transition Elements and Coordination Chemistry, Periodic Table and Representative elements take 3 questions slot. Thermodynamics and Gaseous state, Atomic structure, Chemical Bonding, Chemical and Iconic Equilibrium, Solid State and Surface Chemistry and Nuclear Chemistry and Environment get 2 questions slot eacch and the remaining get 1 question each.In Mathematics, Co-ordinate Geometry gets 5 questions. Limits, Continuity and Differentiability, Integral Calculus get 3 questions slot each. The rest get 2 and 1 questions slot.

Once you complete a topic, try to practise the concepts and write down the important points and paste them somewhere that you can see. Practise questions from that topic. Refer to books like:

Important points:

You need to be physically fit to be prepared for what is ahead of you.

Keep telling yourself that you can. That is important

Make sure you improve on the speed in solving sample papers and quizzes

Take online mock tests

Focus on acuracy and speed as well

Improve your concepts and focus on weaker areas

Short breaks between change of subjects is really important

Do not overstress yourself

Avoid oversleeping during the day but get adequate sleep

Dont get nervous.

Hi Dear,

JEE Main exam is a tough exam as the competition is high and syllabus is vast. To crack the exam proper preparation with good practice and revision is required. I'll recommend you to cover the important topics first and practice as many questions as possible. To start with list down all the topics you are required to cover and identify your strong and weak areas. Pick up the weak topics first and clear their concepts first and gradually pick up the strong areas and give proper time for practice. Prepare a schedule for yourself and divide the number of days in such a way that you get sufficient time before the exam to give a revision to all topics.
