Judging by the names of the two links above, these are word lists for a magazine and a newspaper, yes? I'm fairly certain that there will be a high level of overlap among all the sources. But if you insist on this path, then just stick with the GMAT-specific content for now at least. You could, of course, read some articles from the New York Times
and and Scientific American
. Again, please don't invest too much time on the vocabulary.
