Just ask the students who appeared for NTSE exam or refer a guide that are based on NTSE exams.Or another way to is to refer the NTSE materials that are being provided by various institutions that are giving coaching for this particular exam.I think that is the best way to get to know more about NTSE exams rather than getting the old question papers.

HOPE YOU UNDERSTAND AND I REQUEST TO FOLLOW THIS WAY OF LEARNING.IF IT OS IMPOSSIBLE,REPLY ME BACK AND I WILL TELL YOU ANOTHER WAY OF POSSIBLE.
