With other resources to prepare for the CQT certification exam, it was like preparing in a blind format. Just attempting questions with no reviews. However, with the Quality Technician simulated quizzes, i had a performance record made available online that helped me learn about my attempts in a detailed manner. This helped me analyze my strengths and weaknesses in a way that made me strategize my future attempts. All this made my concepts clear and helped me nail down the certification exam.
