I know that Khan academy focus on North America (mainly the US) for a reason, but some tests for people outside the US are harder than the SATs and the content lacks for such.

Examples of these tests are the Indians ITTs and the Brazilians IME and ITA, which require a deeper understanding and, sometimes, even knowledge of college subjects not offered by Khan Academy or not so specific for such.

As a Brazilian studying for ITA, I find there's little content out on the internet that fulfills my needs that are not extremely expensive or existent, not to say that they usually do not pay for themselves.

As I can mostly say for Brazilians, we have sites such as www.paperx.com.br that have the archives for a whole bunch of previous tests, with a good interface and for free that offer the millage needed, but the knowledge sources lack.

I love the contents KA offers, but it's way bellow the curve for our needs.

Thanks for the time, Matheus Wesolowski
