4 Tips to Success in learning Inorganic Chemistry:
1. Start with the most important chapters such as p Block, s Block, and Chemical Bonding. After that, go on to less crucial subjects based on their weightage.
2 Utilise the NCERT books to their the greatest potential: Most of the time, students do not adequately read the NCERT and instead study from other required materials, leaving them with an extensive curriculum and limited time. You should begin your preparation with NCERT because that is where most of the questions will be found.
3:Take the main exam with the inorganic Chemistry section: Most people do not prepare for inorganic Chemistry because each chapter contains a lot of material and requires a lot of studying.
4:Make a list of all the facts and exceptions in one place to help you revise quickly and boost your chances of scoring well in this area.

Good day, Sushant Yadav. Never forget that anything is possible if you put your mind to it. You must have studied in some capacity for both JEE Mains and JEE Advanced even before today, I'm sure. Create a study schedule for all the topics to be covered in this period, not only for Chemistry but also for other disciplines, using the leftover time. Of course, you can devote more time to Chemistry if you feel sure in your knowledge of other courses. At this point, I'd prefer not to advise switching up the books you've been reading because doing so would introduce an abrupt shift in perspective, which could be distracting for someone studying for a competitive exam.

For entrance point of you, there is nothing like last minute preparation. You need to have thorough knowledge of the concepts because Physics is all about concept and problem solving. But if you are preparing for board exams, in case of Physics do give a preference to derivations because they ensure you full marks if you learn it well. As we know in numericals there are chances of calculation mistake, formula mistake and more so its better to concentrate on concept and understanding before you start strugling with numericals. Another thing I can suggest solve atleast 5 previous year question papers they will help you for sure. And for Chemistry since the weitage of organic Chemistry and physical Chemistry is higher than the initganic Chemistry. Give your preference to physical Chemistry because at last moment its difficult to understand the organic Chemistry and in inorganic Chemistry there are exceptions more than trades it can confuse you at time of exam so don't try to cover inorgainc at last moment. And as I told you for Physics solving sample papers at last moment will be a great decision.
