Hello Ayush,

The sc rank you have mentioned ie 1580 is not enough to fetch you a branch in mmmut. 

According to the stats issued by the college itself it has been shown that in year 2017 the minimum sc rank was 1375 in mechanical department and other departments had better rank for admission 

Same is the case for 2018. Never the less you can wait for the councelling as the rank can vary great to year.

All the best for future!!
