I have found that Roger alone has been more than enough preparation for me. I have passed BEC & REG this year, both on the first try, and am waiting on my score from my first attempt at FAR. Aside from the fabulous videos everyone hears about, I find the book really helpful to flip through and review concepts, and I have found that the practice questions are MORE than enough preparation for me. They have matched up well with what I've seen on the actual exam, and I find the answer explanations with Roger to be very thorough and helpful in my studying! I would agree that hands-on practice is incredibly important in preparing for the exams, but I have found that Roger serves me well in that realm. Additionally, having the solid course behind the multiple choice to help me fill in the holes in my knowledge really helped me out in passing – being able to easily reference the material the questions were related to was SO so helpful to me.
I used roger videos and surgent questions for aud and far. Used surgent only for bec and failed. Not saying its strictly because I didnt use roger, I didnt study enough either. Im using ninja only studying for the retake. Having sat through bec already im finding ninja mcqs most resemble what was on the exam compared to both roger and surgent. In short, ive found rogers videos and ninja mcqs to be my fav combo.
As far as trending scores go they have been fairly accurate for me. Was trending upper 70's in far made an 80, mid 70s on aud and made an 82. Mid 60s on bec and made a 66. My score reports were avg on mcq and stronger on sims in both aud and far so mcq was probably dead on.
