this all comments on jee advanced 2013 are with respect to last years's jee mains exam..

according to my view this year's jee advanced paper was of moderate difficulty..
i thinks that the physics portion was a bit easier this year..
and chemistry was of tough level.. it was quite hard to solve.. salt analysis was having a very good weightage.. students who have choosen to solve chemistry first may have been fucked up..
although maths was a little bit tougher than last year's jee exam..

OVERALL THIS YEAR'S EXAM WAS BIT TOUGHER THAN PREVIOUS YEAR..

i thinks this year's general merit list cutoff of jee advanced will be around 135..
obc may have cut off around 122..
sc/st around 88..
