After looking at the GRE reports, you realize that if you're going to do a post-grad degree, you'ld better get perfect scores on the quantitative section. (Especially if you're from an engineering or science background.)
And you really feel like an ignoramus when you're asked for the antonyms of words such as "excoriate", "potentate", "peregrination", and "puissant".
There is a proclivity soon after to display an ostentatious and pedantic usage of the words learnt. Quot Erat Demonstratum.
