It's essential to divide the exam time across sections and allocate specific durations for each question. Making educated guesses when necessary can help maximize scores while conserving time. Prioritizing questions based on familiarity and difficulty ensures that candidates tackle manageable portions first. Lastly, maintaining focus and calmness throughout the exam allows for clearer thinking and better decision-making.
