Experts at CIVILS IAs advice commencing it at least a year before appearing for the exam, if not more. The earlier you begin, the more time you will have to study, revise and practice for the IAS exam. Plan Ahead Success in the IAS exam is mainly incumbent on detailed planning. Not just the day-to-day schedule but an overall coverage of subject matter too. Identify and lock in the optional subject during this time frame as well.
