BITS admission query

Hey guyz, plz plz help. I have already filled my preferences for courses at BITS. I gave topmost priority to BE’s at Goa, then followed by BE’s at Hyderabad, and finally the MSc’s at Pilani and Goa. My score is 290. But my main fear is that my score is only 2-3 marks below the cutoffs for E&I, Mech. @ Goa, which I really want and moreover, I put the MSC’s behind BE’s at Hyd, where I don’t want to go. I want to ask that is it worth changing the preferences now, considering the fact that I don’t want to study @ Hyd campus as well as having a doubt that MSc-BE duals are given less preference than any BE during placements. Is my doubt true? Plz help as it is the question of my higher education and career.
