In the GMAT Sentence Correction questions, GMAC has tried to minimize cultural bias. Instructors, please correct me if I am wrong. Instead of being tested on idioms, you will often be confronted with two answer choices which are grammatically correct, but only one of which has the correct intended meaning. I am just parroting what I have heard through the grapevine, so I could be wrong. It's worth an investigation.
From Dr. Rudner's post (GMAC)
Regarding Idioms:
"The general categories of language-use skill tested in GMAT Sentence Correction items haven't changed, and test takers do not need to do anything different to prepare for the Verbal section of the GMAT.
For years, GMAC has paid close attention to the growing international make up of GMAT test takers and has worked to assure that the exam is not viewed as - nor is it actually -an American test. As the GMAT exam has expanded globally and been taken by more students from around the world, GMAC has continually made extra efforts to ensure that newly introduced GMAT items do not depend on familiarity with distinctively American expressions and usages. We have taken steps all along the way to ensure global fairness and appropriateness."
Regarding Grammar in Sentence Correction Questions:
"In recent years, GMAT item writers have been concentrating on the reasoning aspects rather than the purely grammatical aspects of Sentence Correction skills. As always, test takers need to carefully read the prompt in order to choose the answer that produces the most effective sentence. This means that while two sentences may both be grammatically appropriate, the correct answer is the sentence that is most "effective," the sentence that better expresses the idea.
The end result is a GMAT exam that doesn't test simply a person's ability to memorize grammatical rules or recognize idioms for their colloquial meanings but a test that rewards reasoning regardless of the test takers background."
Finally, Dr. Rudner closes with this statement:
"The GMAT exam tests higher order reasoning and preparing for the exam remains an exercise in developing and exercising those skills."
