Hello Sandesh,
Firstly, the admission to engineering in any branch including IT is normally not based on marks of 12th but is based on marks obtained in the concerned CET. So, if you study well and obtain a percentile of 80, you will have bright chances of getting your desired branch.

First of all think that ending up with 65% in +2 is not the end of the road. Of course, you may not get admission to some prestigious colleges for your UG. But you could try in some other private colleges for your UG. As you have not mentioned your taste, it is very difficult to suggest a course.

Yes friend, surely you can get admission in DU.

Friend,
Give the supplementary test for Maths and clear the exam. And then you can take admission into Private Colleges all over India.

You can do:
1. B.Pharma
2. B.Sc
3. MBBS
or you can also change your stream and can do B.A.

It you have a good physique, then you can go for Army or Navy entrance exams. You can also do B.Tech and B.Sc. If you want to study further, there are so many options available in the market, so choose that career in which you are interested.
