Hello Sanjay

Yes you are right.

As it is included under jee mains so it's popularity will also increase.

So with this rank ; it may be possible depending upon the demand and interest of other students .how other students response and what are their preference ; it will all matters .

So hope so you may get admission into it ; but chances are less with 340000 rank.

Donot depend only on this have a backup or side option along with it.

So good luck
