Dear Parth,

To fulfill the eligibility criteria to take part in Joint Entrance examination, you need to be passed or appearing in 12th standard with Physics, and Maths as a compulsory subject. After clearing that test you can take admission in any prestigious college to pursue the engineering degree in Computer Science Course.

As you don't have Maths in 12 still you have different ways to do a computer course, You can do BCA (Bachelors in computer application) which is now have equal value as B.tech in Uttar Pradesh, Another option is for you to take admission in B.sc course with computer science where you show and apply your knowledge and interest in computer science.

Hope this will help, All the Best!!!
