I've got 279 in bitsat 2012 (cutoff for physics dual was 273 in goa n 269 in hyd in 2011), but i'm in the waiting list for 1st iteration. Can I get dual phy in goa or hyd in second or third iterations?

tanya yes probably you will get any one of the dual degrees at hyd and goa.infact this year cutoffs have dipped by 8 marks or so it becomes a lot more sure..but as an advice avoid joining hyd and goa if you can get decent NITs.

Try to give  preference in  hyderabad

you can get in Hyderabad
