I don't want to scare you by saying but in RSWL quota,even wl 1 has only 70-80% cnf chance. Even i was trapped in ndls 3yrs back due to rajdhani. My wl was RSWL 1,2,3,4 in 3a for ndls to bls in bbs rajdhani. I got this while doing reservation well before 2 months bt it didn't even came to rac and stayed 1,2,3,4 even after chart prepartion. I couldnt board the train and after dep,i went to ndls station supdt. for a ticket for next first train to bls.
