HI I AM PREPARING FOR IIT MAINS AND ADVANCE. nOW, i HAVE TO ALSO PREPARE FOR MY CBSE 12TH BOARDS.mY QUSTION TO U IS THAT IF I STUDIED THE WHOLE OF OCTOBER & NOVEMBER FOR IIT SOLELY AND THEN FROM DEC TO MARCH FOR MY BOARDS ALONGSIDE SOLVING TEST SERIES FOR IIT, WOULD IT BE SUFFICIENT TO CRACK THE MAINS . wOULD MY DECIDED SPAN OF STUDY(WITH FULL CONCENTRATION), BE ENOUGH TO DO WELL BOTH IN MY BOARDS AND MAINS.

Hi,

It is always advised to study for boards and JEE simenteneously. If you prepare for boards and JEE seperately than ur doing the effort twice.

So prepare for both the exams simenteneously. But How ?
Prepare chapter wise, study the chapter for boards first. Now the theory remains the same every where , so after preparing for boards take a good book for JEE and solve the questions of JEE level.

This will help you in gaining confidance for both the exam and ull save time as well. Dont be in a hurry. Go chapteriwse, and remember whateve u are doing do it completely so that u do not have to come back again to it.

Best of Luck !
