Dear Vishal!
In India! While admission to your Bachelor degree, what matters is your Class 12th marks and the score (or rank) you obtained in the Entrance Exam. As you said that you have many participated in many tech-competition, this helps you while campus interviews. However, you can show these certificate to enhance your face value and to get some additional preference over other students. Hope this helps. Ask any query at anytime. Good Luck.

If you want NIT college, admissions are mostly done through JEE main entrance exam. But, if you belong to OBC category, then you should score above 130 marks for best NIT College. Suppose you got 85 to 110 marks, then you can be eligible for IIIT engineering college.

If you are not aiming for top NITs, a score in the range of 140-150 in JEE Mains will be enough to get into any NIT.

Please specify the exam name for better assistance, because there are many examinations with the same name:
CG PET
Madhya Pradesh PET
R PET
BHU PET

Nope! You are not eligible! They require minimum 60% in graduation!
But, you can apply for private colleges!
Good luck!

No IITs and NITs provide BCA. But Many NITs provide MCA course!
