hello aspirant,

I hope that you are doing are doing absolutely great.

With reference to your above mentioned query, I would like to tell you that you are learning these chapters - Heat, Waves, thermodynamics and Sounds in a very new way, so don't care about some prerequisites in those chapters. There are no prerequisites in these chapters. I know that these chapters are very new and have some unfamiliar concepts for you and also very important for JEE mains examination as well, so first try to go and understand with the basics with these chapters. Because basics are important first.

The suggestions I would like to give you is that solve as many questions as you want in these chapters so that you will hold the grasp on these Important chapters and if you get stuck at somewhere, ask for doubts from your teachers and fellow classmates.  This will clear your basics on these and this will be like the prerequisites for you in class 12th because these same chapters will be there in your class 12th also but in a detailed and conceptual way.

Further, if you are a JEE aspirant, then i would like to share some preparation strategy and tips followed by toppers and experts so that it might help you :

• Give equal weightage to all topics

• Distribute the time needed to study it. Give more time to difficult topics and less to the ones you just need to revise.

• Ensure you have scheduled revision time in the plan

Action Plan to Prepare for JEE Main 2022

• Study a chapter and understand the concepts. NCERT books are good for this.

• While studying, make sure to note important points and formulas. This short notes will be useful during revision.

• After studying a chapter or topic, check how much you can recollect and to what extent you have understood the topic.

• Then practice questions based on the topic studied. While practising do not go for the solution directly. Try to solve yourself, make mistakes and then correct it. This step will help you to know how to crack JEE Main .

• Make sure to give a JEE Main mock test after completing the subject. Similarly ensure that you appear for as many mock tests as you can so that you can analyse your preparation levels, understand where you are making the mistakes

• Use the analysis to know your weak areas and concentrate on improving while revising.

• Be wise and Revise - Without revision, it is difficult to crack any exam especially one like JEE Main. You can only improve if you revise.

• Clear all your concepts, doubts. Never leave a question unanswered in your mind.

• Put the brake and take a break
