Hello aspirant

Hope you are doing great there . First of all you should be well known with the fact that 5 months are sufficient to get a secure seat through jee mains if you are ready to work hard , leaving everything else for the next 5 months , since you have to compete with students who are working hard for 2 continuous years. The next is I would suggest you to do Algebra , Coordinate geometry and chapters like mathematical reasoning and statistics in maths to do first because they definitely give you a no. of questions and once you get a grip in that , you will find them very easy in your exam . Similarly for chemistry I would recommend you to at least learn inorganic chemistry , since the questions from these branches are totally based on your learning and it will also same your time during the exam , since for questions from inorganic chemistry either you know the answer or you don't know . In a similar fashion figure out chapters which you find easy in physics too . Apart from these chapters you have to do some other chapters which you find easy . One more thing for inorganic chemistry is that make a habit of giving 1 hr to organic chemistry everyday . And in the next 5 months you will not find it difficult to learn .

Also try to join dropper batch in coaching institute , since it will not only help you understand the concepts but also they will prepare you for the exam and you will be able to learn complete syllabus in 5 months , you just need to follow your teachers guidance.

I hope my answer helps

Wish you all the very best!
