The CBDE exam presents 70 questions inside a 90 minutes window. That combination makes time a resource you manage, not a backdrop: candidates who never practice against a clock often leave easy questions unanswered at the end. Use the TorrentExam mock exam system — its timing function recreates the real pressure, so you can spot pacing gaps during preparation instead of during the exam.
