HELLO AMIT

both the above mentioned colleges do not accept JEE mains score.If you live in karnataka then you can give two entrance exam to enter into this isntitue or any other good institutes of karnataka.
1.KCET

2. COMEDK

if you reside in some other state do not worry you can even enter into this institute by giving the COMEDK exam which is very much easier than JEE mains and there are no negative marking for it.
i'll give the link of both the exams where you will find all the details like eligibility,important dates application form etc etc...
