yeh, u cant really have a story prepared, coz the question might take u in a totally different direction, but its a good idea 2 have some ideas 4 a bunch of different storys - just general stuff, like characters, situations, different perspectives, issues etc. that u can jumble 2gether so ur not having 2 come up with everything on the spot. oh, and dont just start writing without some idea of where ur headin with it, otherwise ur story wont get good marks 4 structure, plot, logical progression etc. u can play around with perspective 2: like, most storys bout journeys etc. r written from 1st person - try 2nd or third.
