Actually rank required in JCECE for to get Bit Sindri it mainly depends on which branch u want ? If you take core branch then CML rank should upto 400 for general and upto 600 for OBC and for other branch you can take with rank upto 1000 for general ,1200 for Obc and for St/SC You can get admission upto rank 8000 ;

So I can say that for admission mainly depends on choice of branch and category for which rank required is different for different situation since you have scored 8000 you may get this particular college.
