(3) Critical reasoning-they are giving utmost importance to this section,i think it is probably of 30 marks(12 questions),just go thru gre barron 12th or 13th edition model test papers.questions are direct. they are not even changing the order.so just mug,easy ones you can solve,but memorise difficult ones.many of my friends could not make thru due to this section only i am giving some of the questions which i remember.
verbal: chide,dotlish,protract,mawkish,disgeneous,repugance,vouchsafe....
