I'll attach a link below which will have some sample papers of Allahabad University bcom papers. At the same time if you need more, kindly search on google since some other sites are available wherein you can get the papers and due to Careers360 guidance rules, I cannot post those sites here..

And so solve sample papers and previpus years papers both since they help a lot in channelising yourself and analyzing exactly where do you stand, what more you need to study and can also increase  your confidence.

Kindly refer to the sites below..
