This test is tough on time. 70 questions in 90 minutes, passing score 71.4%. Because I didn't get the right book, so even putting in a lot of effort and time, I still failed last Friday (4/26), only scoring 55.7%. I went online to purchase Transender software Friday night, and went over all 210 questions and 420 quizs in 3 days, then retake the test on 4/30 and passed. After the exam, I felt sad: so many hours of hard work seem so useless; a couple of mock exams seem so useful.
