After receiving their UPSC results, candidates should take several important steps. Firstly, they should assess whether they have qualified for the Mains Examination based on their score. If they did not qualify, it is advisable to evaluate mistakes and areas for improvement in future attempts. If they pass, candidates must begin meticulous preparation for the Mains, including selecting an effective optional subject. Furthermore, candidates should consider seeking guidance or joining coaching for interview preparation if they reach that stage, and reflect on their overall strategy moving forward.
