To assist candidates appearing for the UPSC civil services (prelims) examination, Noida-Greater Noida Metro services will commence earlier at 6 am on Sunday, June 18, 2023. This adjustment is intended to ensure that candidates reach their examination centers on time. Typically, metro services on the Aqua Line start at 8 am on Sundays, but the NMRC has decided to adjust the timings to accommodate the exam schedule. The UPSC CSE Prelims 2023 examination will take place on June 18th, starting at 9 am (forenoon session) and 2 pm (afternoon session), and candidates are advised to arrive at their venues 30 minutes prior to the start of the exam.
