Hello Madhav 

CSE and ISE are most sought branches in PES and afterall PES is one of the prestigeuos private colleges for engineering.

So, as far as CSE is concerned the last years trend says that the closing rank for the same is near about 700.

and so is for ISE too!

That is the closing rank would be near about 1K.

but it wont get down to 6854 for sure.

Hope that helps!
