Hii aspirant...

 You will be given choice to fill these two colleges Kalyani Government Engineering College(KGEC) and Jalpaiguri Government Engineering College(JGEC) only if you are having domicile of West Bengal.

 A student having home state quota of West Bengal is only allowed to take admission in this government colleges and all other outside state students who are not having domicile of West Bengal and not allowed to do the choice filling of seat allotment for these two colleges and neither allowed to get admission in these colleges as these are the colleges providing seat only for home state students.

Hope it helps. 

Best of luck for your future.
