Partiallity in admitting files

I am sure that CA Club Management is showing partiality regarding files acceptance. I have submitted last time regarding Nov CA Final coverage by my study material of 90% SFM paper. It was not accepted. Again on 28th, I submitted CS Final FTFM Dec Paper along with 50% coverage information. This was also not accepted.
However, the same method used for CA Final SFM Nov, 2010 submisssion by Nahata Professional Academy on Nov 10th accepted. (showing the Question paper & coverage by the institute)
Why this partiality...
