if u want to go Mumbai ,than its recommend to take GN quota which starts from kishangarh. as its having large potential for confirm tkt if there is more rush than too some how u 'll get RAC. as RLWL does not CNF in many times. especially AC its tough to CNF..
tkt is easily AVAILABLE for (JP- ABR/PNU). if its in WL than to post charting it may confirm.
