This is from IIT JEE 1999. If i remember this was one of the most difficult Math paper in those years.check out question 11 at the end , nice one. Trivia: Check out JEE 1998 paper on physics & try out subjective questions at the end.Boy was that paper hard.

Some questions have more than one answers right and all answers have to be marked to get credit =)

from what i remember 1987's jee maths was the toughest. with the cutoff's in the lower teens or something....

what's considered a good score on the iit?

in 1998, we used to aim for 50-60% on all 3 (P,C,M) to get in top 500 out of total ~2500 seats - all india topper that year scored himself at 85% (they just tell you the rank you have to score yourself later).
