It's important to note that the conditions under which you take the practice tests may be simulated but not perfectly matched-your level of preparation, anxiety, how you feel that the testing environment on test day may influence your scores. So differences between your practice test scores and real scores are not common.
How old are the MCAT Practice Tests, and which one is best?
The current offerings of MCAT Practice Tests were administered as "live" forms in the mid-1990s through 2000. The dates they were administered, however, is really not important. Each test is representative of the current MCAT. Because they are all authentic MCAT exams, they are all good examples of MCAT exams.
