you will easily get CS1P .... EC and EE have lesser chances as they close early and they are lower on your option list too.... technically ... CS1p is the best choice u have got .... as far as i can guess .... ur rank must be 1100-1200 so u stand a chance for CS as till the third allotment it has gone upto 1079.... so u will get it in real time ...before the confirmation of EC/EE .. CS will be confirmed
