DeaR Yash!
Yes it happens..it had happened with me and had been happening in a lot of cases.In 90% of cases I know,it happened,I asked for 2 papers and it happened in 2 of them.
I think you are luckier,because in my case the mark in Results were lower than it was in my answer book.And I got my SFM and AAPE answer books when I was leaving for my FR exam.And I had compared my AAPE answer book with ICAI suggested answers line by line,still there is a HUGE discrepancy.
So,I want to request u not to break ur head in this matter here and concentrate in ur studies plz.If u r an average student just work hard and equally PRAY hard(lol).And never lose confidence in urself because of a person who earns good money but dont have the heart to give required time and attention to ur answer books.They are all called B*******.yeah I stand by my language..
My Best Wishes,
