Hello Dasari Tejeswararao,

You can easily make a time table which satisfy both the jee mains and board exam and also first give important to jee mains because jee mains exam more important than board exam. And first prepare for jee mains ,and complete it before the board exams and also at the time of board exam ,prepare for the board exams. And prepare more previous papers to know which type of questions are coming in the exam and also what type of questions are asked in the exam.Be prepare well for both exams.

Hope this helps you..
