Has anyone tried those leaked real GMAT problems?

Hello Everyone,

One of my friend bought some real GMAT problem sets for study. She said some Chinese websites sell it; basically there are GMAT test takers who memorize the questions from the tests and immediately share the questions on the internet after they finish the test, and then someone compiles all the reported questions to a book.

Anyone has experience with those study material?

Thanks
Mika
