Hello Ankita,

It is mentioned in the brochure of KIIT that they need 60 % in 12 class. Bit it is a private college so  its counselling procedure is not very strict like jossa or bits pilani. I know few students got admission in this college with 50 % marks I'm 12. You can try here. Also it is a deemed university so you can also get into it through management quota and they don't charge extra for that. 

Hoping best for u. Write on comment section of u have any doubt
