Hello Archana,

You've done algebra and calculus part nicely. It's good , but what about trigonometry, geometry and other parts? 

The syllabus of Jee mains is quite vast and you cannot just depend upon two sections to fetch you 60+ marks in JEE mains. Though most of the questions come from these two sections but you cannot ignore the other sections completely. 

Also a good amount of questions come from vectors, three dimensional geometry, co-ordinate geometry, sets and relations, quadratic equation, determinants , etc . Although you may get 1-3 questions from these sections but this will help you to get maximum marks in the examination. 

Just remember the basic concepts of these chapters and solve the NCERT questions. The questions in the exam are generally conceptual and if you have your basics clear and a good amount of practice you can easily get 60+ marks in mathematics section. 

Don't ignore these sections as the questions from these sections are relatively easier . Don't depend only upon two sections as you never know what kind of questions will come in the exam. 

At last I would suggest you to take mock tests as much as possible so that you're habituated with the exam pattern and the level of difficulty of the exam. 

All the best
