Hello,
You have an extremely good possibility of being accepted into an IIT or NIT if you meet the PwD quota. Compared to other students, you need to achieve far lower marks. For instance, while the general cut-off is approximately 120, the general PwD cut-off is about 20.
I advise you to put your quota aside while preparing and concentrate on your studies. If you successfully completed the Jee Mains and progressed, you will get admitted to a very excellent IIT in your preferred branch.
For your query,
Yes, you can get a good government engineering college.
Good Luck !!
