Hello

No need to worry priyanshu, as your score off jee is 45.92 , but if i would know your category  then it would be more better because if you belongs from SC or ST , then ofcourse you can register yourself for counselling through JOSSA .

You can apply to many private universities in delhi as doing engineering nowadays only requires your creative ability to think better and convert your ideas to real world projects , So some colleges i would suggest to you are:

Guru Teg Bahadur institute of delhi

Jamia Millia Islamia (JMI), Delhi

Guru Nanak Institute of Technology (GNIT), Delhi

Sharda University, Greater Noida

Netaji Subhas University of Technology (NSUT), Delhi

you can refer to above colleges as they conduct their own entrance and does not require jee score . If would need further suggestions then feel free to ask from me . If you find my answer satisfactory then respond it .Thankyou
