I gave GRE 4 yr back. Dontt know changes. The langauge section is tough. For RC u need to read atleast twcie and identify what each para denotes. Some words u may not understand. For this u need to go bak 2 ur vocab preparation. If u have prepared 'cards' (5-10 words on one side, meaning on other) then u can revise over them. Once on the day u finish the card, then again after 2 days and after a week and then anytime later. So progressively u will have a whole lot to go thru. U need atleast 3 months for such a preparation.
Maths is easy if u solve barrons.
Writing - u need to understand the different stages of developing a passage. then u cud write on anytopic as long as u know ur flow of arguments/opinions.
