The GMAT is available year-round (nearly every day of the week and at several times during the day on most days), which offers Chicago test-takers great flexibility in scheduling. Do note, however, that available time slots change continuously based on capacity and ongoing registration. Desirable slots fill up quickly, so make sure to register for the exam early (a month or more ahead of time) if you are dead-set on a specific day of the week at a certain time. Illinois has the fourth highest amount of yearly test takers in the country, so don’t wait too long to schedule your GMAT test date. You will find out which times are available at your chosen Chicago test center when you register for the GMAT at MBA.com. If your desired slot is not available at a given center, you can always try another one close by. To avoid added stress, you may want to schedule your testing around such popular Chicago events as the St. Patrick’s Day Parade in April and the Taste of Chicago food festival in July.
