sir/mam i have heard that I E IRODOV is too tough and nowdays it is not important to do irodov to clear iit jee as it is not of the current iit pattern.Upto what extent is it true.

HEY TUSHAR

PLEASE CHECK THIS LINK ONCE AND YOUR ALL DOUBT WILL BE CLEAR

THANKS

@ tushar 
yes , you are correct , i e irodov is not as such required to clear jee , but the thing is it contains some tricky ques which make u think about physics very deeply , 
so, that u can gain more intrest to study physics , and this problem solving skills are most imp to clear jee advanced . 
thatswhy its suggested to do at least 4-5 ques everyday from irodov , to increase your problem solving and thinking skill . 
HOPE IT CLEARS NOW ..
