Prepone ur DOJ by 1 day. Book in 12688 frm RK-NZM (I wud not tell u to book till BPL as its timing isn't good). Frm der, u can book in either Gondwana or SC duronto (if u r willing to pay d flexi fare). Or u can book in Gondwana upto Betul (41 avl in SL) or book in GT frm NDLS (rac 85, which wud confirm 100%). Now d choice is upon urself.
