The probable four semi_finalists in her category are Mary_Kom,Ren_Cancan,Elena_Savelyeva and Nicola_Adams...
Out of the four,Mary has defeated Olympic and Asian gold medalist Ren_cancan before,she can defeat_elena.Her biggest threat to Gold medal is Nicola_Adams.If Nicola_can be the champion,she will definitely more dangerous in London,her native place.
So,Nicola_stand between Mary and gold medal.Mary has to make strong strategy to defeat her..
Hope she does better in the Olympics. She barely managed to sneak in. Neither did the others do well. Pooja knocked out in the first round itself. Sarita can go the the Olympics only if invited. In fact India will have only one bronze medal from the world championships. Nevertheless best wishes for the Olympics.
