Hi Neha,

Almost 2 Lakh candidates take the CAT exam every year and it is very difficult rather impossible to accommodate each and every candidate to their preferable location for taking the exam. This is the reason why the CAT form asks you to fill more than 1 exam centers based on your preference.

Although they try their best to accommodate candidates as per their preference, often candidates lose out on their first preference.

So, to answer your question, No, it is not possible for anyone to select just one exam centre.

Hope this cleared your doubt.
