Hello Shubham,

SIce you are comparing Sjbit, Rnsit ,Bnmit And ksit then if we go according to the placement point of view then 

SJB Institute has a good record as comapre to other three 

Same if we talk about the infrastructure then also SJB institute has a good record 

But in the view of faculty support Rnsit has a better review then Sjbit 

So according to me ranking among them would be :

• Sjbit
• Rnsit
• BNMit 
• Ksit
