Hii dear, 

According to your mentioned marks, you have almost negligibe chance of getting any branch in any campus, but according to last year data of Hyderabad campus the cut-off marks was:

• Chemical engineering - 257
• Civil engineering - 258 
• ECE - 298 
• Mechanical engineering - 275

And  by comparing some previous year data then we found that  the cut-off decreases generally . But, I suggest you to start searching for some other colleges rather than expecting of taking admission in BITS. 

So, I wish you All the Best and choose your college wisely. 

Thanks.
