JaniceHelton 0 Posted April 18, 2022 Using the atlas is a vital step of preparation, although we would have been negligible towards atlas in our school days, the same can't be applied to UPSC preparation. Moreoer there is a small correction in the question, atlas map helps all the way through prelims,mains and personal interview and also in your career as a civil servant, so there is no separate preparation style for prelims alone. njmcdirect Share this post Link to post Share on other sites
