Hi Joginder,
Hope you are doing good.
Rating of V. Good/Excellent is usually for question paper with answers.
You possibly have got comment as excellent because of clean and latest question paper.
1.Regarding authentication of question paper, Well we trust on our members, in case some user complains about fake paper we can investigate and take corrective action, Also its not possible to verify the authenticity of every single question paper.
2.We are in process to decide a new completely changed rating system and a detailed FAQ section for do and don't, This new process will be transparent and clear.Mean while simple tips are, Submit text papers rather than PDF or image attachments, Question papers with answers and latest question papers.No copy paste from other sites.
3.Very nice idea,Have added this in payment methods, to enable this option go to
