Muhammad Midlaj, 

Last year cut off rank for Muslim category in 6 round in JMI was 

Civil Engineering 62011

Computer Engineering 35303

Electronics and Communication Engineering 55163

Electrical Engineering 60226

Mechanical Engineering 60029

As you see there is difference of 1000 rank in cut off rank and your rank but still you can get mechanical engineering as the rank will get dropped to 70K in spot round. 

So no need to worry;)
