Friends my name is lakshman , I have studied in narayana school from 9 to 10 , and college of class 11 and class 12th. At first in NARAYANA olyampiad school the will teach u objective questions from class 6 and in the narayana iit books there are upto 5 level of bits , the iit books include maths , physics, chemistry .They cover all the topics from every standard. The use of this objective is mainy, you can solve jee-mains bits , eamcet bits , ntse bits , etc; by practicing from the school it will be easy to slove bits in class 12 , the narayana iit books , the bits are from the past 10 years of every exams , so the narayana olympiad is step to better future
