Dear candidate.......

Well, securing 3039 rank in CEE 2019 may not be sufficient for getting admission in a government college for B.Tech mechanical engineering. But still you can give it a try at the time of counseling since you're a ST candidate . And also if you're a resident of Assam, then home state quota can also be applied.

But there are also several constituent and private colleges in Assam where you can apply for opting mechanical engineering.

Hope this helps.......

All the best:)
