Hello,

Along with hard work, smart planning and effective execution is also necessary to score well in JEE Advanced exam. You should manage your time well on day to day basis and try to strengthen and clear your fundamentals. Divide your preparation as per months so that you can finish your syllabus in time and also have time for revision. Revision is necessary part of the preparation. Solve previous year question papers and give mock tests to analyze your preparation. Youcan definitely score well by following a scheduled time table.
Arihant and HC Verma are good books, you can lso refer to books like
