sir,can u please tell me when will be the answer key for online mode exam will be released which is held on 9th april,2017

It seems that the computer based examination of JEE Mains conducted on 8th Apr 2017 is easier compared to the pen and paper based exam conducted on Apr 2nd. In that case, the students who opted for pen and paper based exam on 2nd April are at a disadvantage, both in terms of time (one less week for preparation) and increased difficulty. Would CBSE do any moderation between both pen and paper and computer based tests to bring students onto the same ground ?

When will the solutions for online exam on8 April be available ??
