Hello Friend,
Number of Attempts and Age Limit for Appearing in IAS Exam 2017. For General Category candidates, the new age limit is 32 years and the number of attempts is 06. For OBC Category candidates, the new age limit is 35 years and the number of attempts is 09.
Now, candidates are allowed a maximum of four attempts, if they are between the age of 21
and 30 years. On the other hand, candidates belonging to Scheduled
Caste (SC) and Scheduled Tribe (ST) categories have no limit on the
number of attempts and are also eligible to appear for the exam till 35 years.
Hope it will help you!
