IITJEE 2011:12 MARKS FOR FREE FOR WRONG QUESTION

IIT-Kanpur, which conducted the
joint entrance exam, said three
mathematics questions have
been declared open. It means
every student who took the
paper would get 12 marks free, a
move that will raise the cut-off
for mathematics.
It has also been found that three
questions – two in mathematics
and one in physics – had all the
four choices correct. Out of eight
questions with wrong,
ambiguous and incomplete
descriptions, six worth 22 marks
are in math and two of eight
marks in physics. This is the first
time that IIT has released answer
keys before the final results are
out.
