Most experts recommend the students to study for around six hours a day excluding that time which they spend in coaching classes. This can only be useful if you design a timetable that suits your schedule.
Mastering only the concepts of physics, chemistry, and mathematics to crack JEE is not sufficient. You need to practice the time management and motivate yourself. One f the topper of IIT JEE says, “I neither had a fixed timetable nor a number of study hours to study for JEE Main & Advanced Exam. I studied what I felt was required to be covered in a particular day. Some days, I would study for 3 hours and other days for 4, 10 or 12. I used to do it according to myself. But on an average, it should be around 6 hours every day. Plan it in a way that you have some aim to cover something and try to achieve your aim for the day.”
Preparation for JEE is a Marathon, so you have to be patient and calm. It is not enough to promise, you will study for 10 hours a day and eventually lose steam in two weeks. Studying in a focused manner for six hours a day for 8 months will ensure a better chance at success than cramming for 12 in the last few months. Also, you need to stay away from distractions while preparing for JEE.
Attempt mock tests, solve previous years question papers and go through the JEE syllabus thoroughly. It will help you figure out where you stand and identify the areas where you need improvement.
If you face problem in maths, design a timetable that almost three hours of the day are fixed for that. Revision is a must. Spending four hours a day learning new concepts and two in revising what you learned is the actual way.
If you find easy concentrating early morning in studies, then wake up early and study at that time. Else, choose an evening slot to study for at least three hours, in an uninterrupted manner.
With consistent work and dedication, no goal is too big to achieve. Stay positive!!!
