as Darshanbhai said "....sale sab agento ne book kar li,corruption .......:( " , agents have booked tickets for either for genuine passengers and also for Fake ones... for some business...
If you will observe the trend, the last day (day of travel) WL will move up very quickly, as agents do not find 'buyers' for their tickets, cancel them...
Hence book even WL will get our genuine passenger move up and have chance of confmd ticket....
And...
more... he rightly said "Agento ne book kar li" means agents are having chance of getting buyers or NO buyers..
