Expect 55-60 questions with a time limit of 90 minutes. The smart move is to treat time as a resource: allocate a rough budget per question, mark the stubborn ones and move on, then return with fresh eyes. Two or three full timed runs in the Lead2Passed desktop engine — which recreates the real exam environment — will calibrate your pace far better than untimed reading ever could.
