Hi Fred,
Have a look at my scores in the practice exams and tell me what do you think. I thought I was well prepared after I took the practice exam 2 but yesterday I failed in practice exam 3.
I don't see a major problem with your scores. In fact, you should NEVER rely on the scores you obtain from Examlab practice exams. If you want to rely on something, consider the score predictor, which is good at making accurate predictions. Currently it reads as you would score around 79% in the real exam, which is above the passing score!
I suggest that after you take the Practice 4 and Final exam, consider repeating some of the exams to make sure if you have correctly followed through the notes you should have created on top of the exams you completed.
