Hello Tushar
Admission for BTech is done mostly on basis of entrance test and jee mains is the most important exam which provide admission in many colleges ; some college conduct their own entrance .
And nearly all the entrance exam has been oven ; now the results of some are remaining only .
Admission will be done through counseling process ( allotment of seats according to the rank and preferences filled by students ) . Couseling will be start from mid of June ( vary according to college and organisations and colleges under a particular couseling ) and it continues till mid of July .
All the admission is done before mid of August ( vary according to specific college ) . Some college give admission on basis of 12 th percentage ; so no need to give entrance .
So you should search about that specific college about which you want to know.
Good luck.
