Prepping for the CQIA Exam

Hi, I just bought the materials needed to prepare for the quality improvement associate certificate and am feeling overwhelmed by where to start. I have the ASQ CQIA handbook, self-paced course, and question bank. For anyone who's CQIA certified could you weigh in on how you prepared for the exam and how long your timeline was from start to finish? How has this certificate helped you in your career?
