Hello aspirant,

There are around 4_5 wrong answers are given in Answer key for 9th January Shift 2.
I think 2 questions in maths have the wrong answer according to the official key.
Q.8 of this answer key provided by Allen though reso has given option 2 to be correct which is also correct according to the official key  there is no official news yet.
There was a question in physics related to the double slit experiment. The answer to that was coming out to be 4.81 using formula as given in Allen answer key  so approximately 5 but in the official answer key it is given as 4.
Then there was a question in maths related to functions injective/surjective  To that, the answer given by resonance answer key matches with the official answer key but the answer key is given by allen says the question is wrong as the range for the function cannot be the one given in the question.

Hope you understand,
Thank you
