The New York Times highlighted a sample of the changes coming:
The SATs rarefied vocabulary words will be replaced by words that are common in college courses, such as empirical and synthesis. The math questions, now scattered widely across many topics, will focus more narrowly on linear equations, functions and proportional thinking. The use of a calculator will no longer be allowed on some of the math sections. The new exam will be available on paper and computer, and the scoring will revert to the old 1600 scale, with a top score of 800 on math and what will now be called Evidence-Based Reading and Writing. The optional essay will have a separate score.
