Hello.

As per new rules being drafted into the Indian education system, currently, no reputed or government colleges takes in students for engineering based solely on their Class 12 score.

Of course, class 12 mark is necessary in the sense that you have to score a minimum mark to be eligible for the entrance exams conducted by the government institues, and a number of private ones. For example, minimum 75 percent to sit for JEE mains.

However, there are of course a few private institutes which will take you based on your class 12 score. Do apply to them, but they are mostly new ones, not reputed and high fees.

Good luck.

Hii aspirant
To get a good engineering colleges like iit or NIT you need to get a good score in JEE MAINS and JEE advance
Or you have to give your state entrance exam
Many private colleges also conduct their own entrance like VIT, MIT etc
On basis of 10+2 marks you cannot get government college so you can go to private colleges where They do not consider JEE or any other entrance
