An in-depth discussion of the content and timing of the MCAT appears in the Application Packet; you should review this material closely. Your scores on the MCAT are an extremely important aspect of the admissions process. You should not take the exam unless you have had ample time to study, as a poor test score can severely impair your chances of acceptance — even if you are an outstanding student.
Therefore, even though the MCAT is administered in several foreign countries, we generally do not recommend you take the exam while abroad. Only if you are an excellent standardized test taker, have outstanding grades, and have sufficient time to study, should you even consider taking the MCAT while abroad.
