The JN0-349 exam gives you 90 minutes to work through 65 questions, so the clock moves faster than most candidates expect. Keep a steady pace on every item, flag the ones that stall you, and circle back with the time you have banked instead of getting stuck. Time pressure is mostly a rehearsal problem: run at least one full timed mock in the TorrentValid test engine before your appointment, and the real countdown will feel familiar rather than threatening.
