how to prepare jeemain in a monthand how to practice
I would suggest you to make a proper timetable and stratagize your work. Don't just blindly study without knowing the weightage of the topics. First decide your own weak areas and start working on them so that atleast you can solve a basic question if it comes in the exam. Practice more mock papers to know your mistakes and rectify it accordingly.
I always believe JEE Main is more about startegy than hardwork. Get you basics right, a proper test taking strategy, revision notes and material for last month strategic preparation as well as a regular study routine with weekly test series and attempting good mock papers and analyzing the solutions.
Though difficult to complete in a months time, but lt me suggest some of the best Last Month JEE Main Prep Material to you
