The UPSC mains exam is a completely different ballgame compared to the IAS Prelims exam. To excel in the IAS mains, candidates need, apart from knowledge and analytical abilities, the know-how to write answers within the prescribed time and space limits. Answer writing is an art and no matter how erudite or how intelligent a candidate is, unless he/she expresses what is expected in the answer booklet, clearing the mains exam will be a rather long shot. This is why it is important to not only study all the right material for the IAS exam, but also practice answer writing in an exam-simulated setting. This will help candidates understand the nuances of answer writing such as how to write what exactly is asked, how to limit the words to the prescribed number range, how to highlight important points and keywords, how to augment answers with illustrations wherever necessary, and so on. Candidates will also learn how to prioritise their answer writing, especially when there are choices. This will also give candidates the much-needed writing practice with which the speed of writing can improve; and during the IAS mains exam, time is always in short supply!
