Hello, I'm currently going to be a sophomore, and I'm pretty much freaking out about the GRE right now. I just ordered a book, Official GRE Quantitative Reasoning Practice Questions, to hopefully brush up on my math skills for the next few weeks, then move on to the other books/test prep. I hope to be able to go to grad school straight after my undergrad years, but don't really know how it works (but that's for another thread I suppose). Back to the topic, I'm not the best at standardized tests. I was just wondering, when did you guys start studying? I know I should have probably started last year, but couldn't find the time. I always hear how the GRE compares to the SAT, but how does it compare to the ACT? If you want to go straight out of your undergrad years, when exactly do you need to take it by (when in your junior year did you take it)? How much do colleges look at the score? Like I said, I'm not the best at standardized tests, but I do have quite a bit of experience. Right now, I'm considering schools such as the Unversity of Montana, University of Idaho, University of Washington, Southern Illinois University, University of Colorado Boulder, Northern Arizona University, etc. What score do you think will be needed for a Forestry/Wildlife Biology masters? Do you have any tips for taking the GRE? (Kind of unrelated) When do you start visiting labs/emailing professors that you're interested in? Since I'm still freaking out a bit, I can't really think of anything else, so I guess this will be it for now. I really appreciate any help/input, I know that some of you were in my place, I hope haha.
