I can't find any definitions on this prep phrase. Here're some usages:

Just as with GMAT books, each GMAT instructor has his or her own pedagogical.

As with most standardized tests, preparation is the key to getting a good score.

As with any statistical summary, one must consider the margin of error.

So is "as with" used for comparison? It's not exactly similar to "like".
Is the meaning almost like: as is true for A, B is also true?

Thanks
