Some more advice in regards to preparation would be to go to the online poker forums that have vast archives and read up on hand histories, situations, and the advice that these people received in their quest to improve their own game. In addition, a couple of poker books geared specifically towards tournament strategy might be worth investing in .If you don't want to buy any books, you could try the local library (a lot of libraries share their book inventories and you might be able to obtain them on loan for a 2 week period of time even though your library does not have it on their shelves).

You have plenty of time to work on your game online as well as to read a few books and gain some advice in that way too. Good Luck
