For Synonyms practice all Word List exercises of GRE BARRON-12th Edition with heading Synonyms.No need to mugup the meaning of all words.You just keep the true option of respective word in mind because the words wih options are just copied in question paper.So if you have previously seen a particular word then u can resemble it in exam and can choose correct option.

For Antonyms practice all Word List excercises and Model Test Paper(given back side of GRE Barron-12th Edition) of GRE Barron-12th .If you practice only Model Test Paper’s Antonyms then you can answer 6 ques out of 10 during test.

NOTE: you skip words with heading “Synonyms and Antonyms” given in Word List excercises. Sentence Completion are also from GRE Barron but it in the form of a paragraph with combination of 5 or 6 sentences. If u have time, practice it otherwise skip it.

RC is from GRE Barron-12th .Practice all Model Test Paper’s RC if you have time.

Quantitative Aptitude(38 ques in 40 min):
Note: For this section there is no need to solve any book you just solve as many questions of previous years as possible.All ques are either repeated or data is changed. Therefore you must know the methods to solve those questions,it will help you if you forget the mugup answer or if data is changed.
