Hey Saran Teja,

Yes for your rank you have maximum chances to get Mechanical specialisation at OU. However as the first preference is given only to the GATE rankers at seat allotment And  as there are only few seats intake you may also not get The seat. But based on the previous year closing ranks you have maximum chances to get the Mechanical specialisation at Osmania University or JNTUH.
