Hello there,

Considering you from general category as you haven't mentioned your category. if we compare your rank with previous year's cut off rank which was around 15792 for mechanical branch it is quite difficult for you to get a seat in SITEC. However you can use the 85% state quota if belonging from the state. Also with this rank you have pretty nice chances in other good engineering colleges in your state.
