[b]1. COLLEGE BOARD:[/b]
The best is College Board because that is the organization that prepares the SAT in the first place. They have a lot of resources for preparation; they even have simulated full-length tests. Their content is usually updated to suit the latest requirement of the test. They additionally provide answer’s explanations for better understanding and concept clarity.

[b]2. KHAN ACADEMY:[/b]
The next best is Khan Academy; they are the official partners of College Board and a lot of students have been following their test preparation guides for their SATs. They cover all topics in depth and provide tutorial videos and test material that comes in handy for clarity on topics.

You have written a post on TestprepKart - This is also a largest and popular site for SAT preparation by NRI students in whole gulf region. They are very popular among the NRI students here. Most of the faculty are very good, i personally had a chance of getting some demo sessions initially, which i liked it and then finally enrolled with them for the SAT subject course for 90 hours.

Once you interact with the TestprepKart's counselor's i'm sure you will be elated with the type of information they give you. Its a completely practical thing.

So, my recommendation to NRIs for SAT preparation is TestprepKart - You get all high end indian teachers with them. Great.
