I prepared it for myself last year. You can buy some self learning guides, like Kaplan, Princeton review or the official guide for GMAT published by ETS. All these books can be bought from Amazon.

Besides, you can also borrow them from the public labrary. ( but the newest version of these books can only be read in the library )
Some books from New Oriental, if you can manage to find some, may also be helpful. Good luck.
