Studying for the GRE

Tomorrow afternoon I am going to be taking the GRE test for the first time. I am wanting to go to graduate school when I get done with my undergraduate at Mississippi State. My undergraduate degree will be in Landscape Architecture and I am wanting to pursue my masters degree in Urban Design and Planning. I have been studying these GRE prep booklets all day and from what I have seen the test is going to be difficult. Wish me luck!
