CAT 2018 will be conducted in test centres spread across 147 cities. Candidates will be given the option to select 4 test cities in order of preference. Cities and centres will be assigned to the candidates only after the last date for CAT 2018 registration.
CAT 2018 exam authorities will try their best to assign candidates to their first preferred city. In case it is not possible, they will be assigned a city following their given order of preference. In the rare case that a candidate is not allotted any of the preferred cities, he/she will be allotted an alternate city. However, candidates will not be able to select the test session, it will be assigned randomly.
