hi,

see there is no free admission, however financial aid is available to students for economically backward back ground and reserve category candidates. however aicte has gate scholarship, you would get monthly 12400 as a gate scholarship. per semester fees is around 40k+  with hostel may vary institute wise , so if you sum up the scholarship amount you would have  a fair amount of money left after paying the tuition fees.

you may also do part time or remote work or internship while studying.

hope it would help.
