I find the tab "observation" in the americanscientific.com, in the above website, contain many articles very similar to those in the gmat tests.
in the articles, the sentence structure is as long as that in the gmat reading passages. The contents of the articles are also similar to those of gmat passage.
apart from reading the economist
, I see that the above website is also very good.
please, give your idea of my reading material.
If anyone in this gmat forum is in England,Britain, pls, email to me, (email@example.com) . I have some questions and need your advise. Thank a lot.
