Your state of mind is a key factor in your success on the CCENT (ICND1) exam. If you know the details of the curriculum and the details of the exam process, you can begin the exam with confidence and focus. Arrive early to the exam. Bring earplugs in case a testing neighbor has a bad cough or any loud nervous habits. Do not let an extremely difficult or specific question impede your progress. You cannot return to questions on the exam that you have already answered, so answer each question confidently, and keep an eye on the timer.
