well its a dauntin' task if you really wanna score big!!!! the only suggestion I can give is just cram up the words..its important that u know in what context these words are used.....as far as preparation is concerned Baron's book will help you build up your vocabulary as it provides examples of same words used in different ways... Apart from that you need to start reading stuff....try to understand difficult comprehension passages....take your time coz u're not takin' a test rite now...but try to finish a passage while u're practicing..go with yor instincts at times...... Go to GRE website...take the full test....and mind it...finish the whole test..even though its sickenin' ...!!!! I think they send u CDs once u register for GRE...take all those tests...and try to finish them on time.....!!!!!
