Worth it

I took the exam and passed it today; this was my second attempt. Some of the questions were verbatim from these practice tests. There were many questions that I have never seen before and I struggled in finding the right answer. I revised and repeated the practise exams until I consistently scored 90% and above, and I think I might have taken the practice exams close to 20 times before I was confident enough to sit for the actual exam. This is a great way to study and learn the material.
