There are only a handful of trigonometry questions on ACT Math, but you can still prepare for them by reviewing the Additional Topics in Math section under SAT resources and the Trigonometry videos under Khan Academy's Math resources. There are also two differences to note between SAT Math and...
–Pick up where you left off: Your learning syncs between your Android and khanacademy.org, so your progress is always up-to-date Learn using videos, interactive exercises, and in-depth articles in math (arithmetic, pre-algebra, algebra, geometry, trigonometry, statistics, calculus, linear alg...
Khan Academy GRE videos can help explain difficult topics, but they don’t go over the format of the GRE or the types of questions the test contains. For that, you’ll need to use other resources. Using practice tests (both official and unofficial), prep books, and vocabulary resources in...

it's not clear that the schools will be able to cope. the very concept of grade levels implies groups of students moving along together at an even pace. so what happens when, using khan academy, you wind up with a kid in fifth grade who has mastered high school trigonometry and physics...

Here is what Khan does know: algebra, statistics, trigonometry, calculus, computer science, biology, chemistry, astronomy, physics, economics, and finance -- well enough, at least, to demonstrate the concepts via brief video tutorials on Khan Academy, his free learning website. What...
