Ah here we go, courtesy of Wikipedia. I remember writing an article on this for the HS paper a few years ago.
In March 2005, the SAT Reasoning Test will be modified and lengthened. Key changes include the removal of analogy questions and quantitative comparisons, the addition of a writing section based largely on the current SAT II Writing Subject Test, and the expansion of the mathematics sections to cover three years of high school mathematics. In all, the new SAT will contain nine sections, and a total length of 3 hours 45 minutes; with the additional section, a "perfect" score on the new SAT will be 2400.
