Yes there are many colleges which are taking students who have not given any entrance exam ...but you have to pay a huge extra amout so alled donation to get admission.
There exists a management quota in every college that sells some of its seats left at a very high amount...even 10lcs sometimes. In this students with 50% also get admission.
I would suggest you to guve entrance exams and earn a seat in any college rather than doing such bad things.
All the best

Hi deepak,

yes sure you can get admission in btech without clearing any entrance exam .There are many private colleges which offer direct admission after your 12th standard so just google it to find list of colleges.

Thanks
