I used Meldrum for L2 and LevelUp for L3 and comfortably passed both. For me, LU was a better overall program, because the videos are combined with a very good slide book which made the learning process effective for me. Meldrum may have added a slide book, and it is probably good, but LevelUp’s materials had a big head start. I didn’t use Ronen. Overall, if you’re willing to put in the time, do the studying, practice problems, old exams, and work their system…then you can pass with any of these guys. This is clearly a crowded and competitive space, no one will survive if they are not delivering results.
