Hey Aspirant,

Unfortunately at this rank in JEE mains you won't be able to get into DTU mechanical engineering. But you might be able to get CIVIL Engineering in DTU and you can get it changed by scoring good in 1st year.  Also if you want there are many other good colleges too,  you can try them too.

For your reference I am providing you with a link to predict a college through JEE Mains rank
