Download a free practice MCAT from the official MCAT practice test website, www.e-mcat.com. If you wish, you can download additional practice tests from the same site for an additional fee.
Prepare your examination area. Choose an area where you will not be disturbed, such as a private office or study room. The MCAT can take as long as five hours and 25 minutes if you use all of your break time; your practice routine should simulate these conditions.
Clear your desk of all extraneous items apart from your computer, ear plugs, a pencil and a scrap piece of paper. This is all you will be allowed when you write the actual MCAT.
Choose either the timed or the untimed version of the practice test. To ensure you are prepared for the actual conditions of the MCAT, you should do a practice test timed at least once, and use an untimed test for review purposes.
Begin the test. Depend on the timer on the practice test on your computer and do not rely on any clocks in your test area. It is not guaranteed that your testing center will have a wall clock in the testing room.
Complete the optional tutorial section at the beginning of the test. This will give you a feel for the test itself and the computer interface. You will also have this tutorial option when you complete the actual MCAT. After you complete the tutorial, take the time to read the Examinee Agreement, which is also a required part of the actual MCAT. Knowing the agreement information ahead of time will make it easier for you to read and understand this section when you encounter it again on the actual MCAT.
Complete all remaining sections of the MCAT. Use your judgment as to whether you feel you need to take any or all of the three optional breaks available to you. You are permitted to eat snacks during these breaks when the actual MCAT is administered. Therefore, you may wish to try different routines if you do several practice tests to assess whether you find breaks help with your energy level or distract from your focus.
