This tip derives from observations of an exhaustive list of PNRs of this train and also from personal observations. Exceptions *might* occur in future, but so far I've hardly come across any such.

In 3A, while booking if the status is GNWL AA/BB (for example in the status GNWL 45/78 AA=45, BB=78) , if the figure 'BB' is below 100, your ticket will, in 9 out of of 10 cases, come down to RAC at least, if not confirmed. So go ahead and book it!

3A mein booking karte time agar status GNWL AA/BB hai (jaise status GNWL 45/78 hai, AA=45, BB=78) aur 'BB' ka number 100 se kam hai, toh tumhara ticket, 9 mein se 10 cases mein, kam se kam RAC pe aa jaega, agar confirm nahi hua toh. Toh aage badho aur book karo!
