Hello debayansen.ds.ds,

Well, as per the previous year's trend and comparing it to current year's jossa stats:

there is very low chance of you getting ECE (in 2019 josaa last round closing rank was  167441and this year it is 113082 so a drop is seen and so will be in csab), previous year CSAB closing rank for ECE was 167441 and chances are for a drop in this year too!, so definitely there is very less chance for you...

Hope this helps, and feel free to ask any further query...
