hey sheetal this is bhargav , i am scheduled for 20th March , u have to do it very hard.. coz hardly have time.. , complete your barron's as soon as possible and also do not forget to revise them everyday.. , suppose u have completed first 10 lists then before going to the 11th read all the 10 lists , and try to remember them .. keep a pocket dictionary with u and read it all , as and when u get time , do not see the meaning first but first look at the word and try to guess the meaning , and once when u are firm with your guess then only see the correct meaning this will give u an idea how fast u can guess.
u can also learn greek roots from "Word power made easy -norman lewis" thats a good book and also contains good list. but barron's is the best.
once u complete this then u can go for big book.
give 15 days for verbals and rest for other topics ...
all the best..
