*Make routine or timetable :- you can make a routine as well and try to give at least 8 hours or more to study , your routine should revolve around things i.e study, revise and practice

PHYSICS is the  toughest part for most of the aspirants  as it has both numericals and concepts to deal with , so keep at least 3 hours each day for Physics.

In Chemistry you have to deal with reactions and learn them and solve questions as well, so give at least 2 hours daily to Chemistry

Mathematics is all about practising questions, so try to give at least around 3 hours each day for maths

*Set daily goals like I have to cover these many topics today, weekly goals like I have to  cover these chapters this week and  solve their mcqs too by the end of this week and similarly set monthly goals to cover the syllabus and meet them without any fail.

*After completing each chapter , you should go through mcqs and numericals of the same chapter

*Make short notes of important formulas and concepts for each chapter and Keep revising it

*Solve previous year JEE MAINS questions , it will let you know the examination pattern, type question etc so that you can prepare accordingly

*Go through JEE MAINS mock test papers , it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination
