Test Preparation

I'm at the local library right now but their collection of test prep materials is lacking to say the least. I'm a student with big dreams but admittedly smaller pockets. My mother simply doesn't have the disposable income to help me, but I don't blame her, she truly tries her best. I'm trying to buy this test book most of all. http://www.amazon.com/gp/aw/d/0764147056 God bless you all. I live in Brownsville. Google it please. It's the southernmost city in the United States, we are immigrants among immigrants. Any available jobs of ANY kind are always given to men who are trying to keep their families afloat in this new land. As you can imagine, standardized testing takes a backseat, and doesn't even cross most people's minds ever. All I'm asking for are. test prep book, I hope you can understand. Thank you
