Thank you so much for A2A.You can fill that form, but let me give you a heads up in advance that chances of you getting an SSB call depends on your combined marks in PCM and not just chemistry. After all the applications reach DMPR( Directorate of Manpower Planning and Recruitment) a minimum cut off will be arrived as per the number of vacancies. If you are lucky enough to make in to that cut off or above you will get a call.But let me also alert you to not be too optimistic, because the lowest percentage that I have heard for the cut off (PCM) till date is 75%+. So be prepared for that as well.Wish you all the very bestJai Hind
