Hello Pankaj,

   After 2015 government has removed the option of admission in IIEST through WB JEE, so if you are looking for admission in IIEST then you have to apply for JEE Mains and also you have to secure a decent rank in that exam. Also, from 2014-15 onwards students who have got admission in IIEST have to complete complete 5 year program that is B.tech and M.tech both. So, for admission in IIEST you have to sit in JEE mains along with scoring a good marks.
