Hello

There are different criteria for different PSU's.

Each psu is having its own criteria for percentage.some ask for 65% and some 60%.

Also few psu's give relaxtion category wise.

And psu calculate your marks as total marks from semester 1 till semester 8 divide it by total marks.

Not as provided by university criteria of 25,50,75,100% in 1,2,3,4th year respectively

Most of the PSUs require atleast 60% of overall engg. aggregate.

But there are also few top PSUs who require 65+% engg. aggregate. There are only 2–3 PSUs which accept 55% aggregate.
