FROM WHERE CAN I GET MOST LIKELY QUESTIONS WHICH WILL BE COMING IN FORTHCOMING BOARD EXAMS OF 12^th SCIENCE?

@ XAVIER 
kindly specify the subject , and the previous year papers are most imp with respect to the board exam level . 
if u will follow the trend of last 5-6 years of paper , then 40 percent of question are of same type with a minor diffrence . 
so, frst of all practice those prev year paper from askiitian , rest askiitian have given some sample paper to solve for all subject , solve that
if u have more time , then go for the sample paper of osswal publication , i found many questions this year from their . 
BUT FRST PREV YEAR QUESTION , 
AND FRM NOW DNT GO FOR SAMPLE PAPER , GO WITH NCERT EXERCISE AND THEORY READING 
ALL THE BEST ..
