From Quora: My answer to: "How can I study for the SAT alone in a foreign country? Are there any online lessons for SAT that anyone knows about?"
As the other answerers have posted, you can use the official College Board SAT practice tests, available online, as well as the Khan Academy SAT prep videos. Many SAT prep books, including Barron’s SAT, can be obtained from Amazon.com, anywhere in the world. There are also many online prep courses available from many providers, including Tutoring by John Linneball.
