text: You should take the PSAT in 10th and 11th grade...most schools have them in those grades. It gives you an idea what it'll be like, except it doesn't have the writing section like the real test does.\n\nThe real test is very long and the writing part is about 25 minutes which is really short to gather ideas, but oh well...you can't change it so just get good at it. I have problems with math myself, it was where I scored the lowest. But you have to start practicing Algebra and definitely Geometry now if you want to do good. I wish I had paid more attention in Geometry.\n\nIf you decide the SAT is not for you, there's always the ACT, which most schools take. I'd take both...I heard the ACT is easier and more straightforward. I'd take the SAT's at least twice and maybe an ACT. Get an SAT practice book so you know what it's like. Only one test is required though. I'd take one SAT as a junior (June), and one as a senior (October).\n\nStart working hard now, that's my best advice!
