I passed my test on the second try. I have to say that after purchasing the Exam simulator to ensure a passing grade on my second try...I was super relieved. The ITTO Practice Exam was key... that 4 hour test exam was absolutely what helped me pass the test. Once I passed that test everything else fell into place. I was so calm and ready for the exam that when I was taking it, it felt just like every other test exam I had taken with the simulator. I had much better performance and less anxiety! I've already recommended OSP International Exam Simulator to all my friends!
