there no similar pattern at all.paper is different for all campus and all most all que was time too time consuming and maths puzzle type.in our exam all most 3 to 4 que was of time and work.3 to 4 about number funda like perfect square,last 2 digit. one was Sudoku and 3 -4 like Sudoku puzzle.some of the que was dummy that have no ans.
my advice,
don't wast much time in tough que,if not gatting ans than just skip.it may b dummy.try too read almost all que at list once,u will find some easy at last.if u don't know ans than just skip.data of same que of ur neighbor may b differ so,not try to copy.
