I have used Ninja 10 point combo, Wiley book and Roger CRAM for BEC.
Wiley- worthless. Its just lacking too much and/or you need to read between the lines a lot. Not helpful on this kind of exam.
Ninja MCG – worth its weight in gold. BEC is the one you really need to understand what you can understand and memorize the rest. Ninja BEC has something like 1400 MCQ I think? If you get to where you can answer 85% of those accurately you'll pass.
Ninja Plus – Bob is the only one I really seem to learn much from. He's great in FAR and good in his section in BEC. The others, and this is purely personal, I just have problems learning with. They present a LOT of information though.
Roger – entertaining and comes with a physical book I can read. I'm too old I guess (34) and I like to hold my reading material, not have e-books and e-notes.
To actually answer your question… I think Ninja MCQ and videos will get you there as long as you really hammer the MCQ and understand what you get wrong. If its facts memorize it, but if its calculation or theory you really need to understand the why behind it.
The only downfall on all of them is they are lacking in information tech (IT). I'm waiting on my third BEC score right now and IT was drastically over tested in every single one of them. I have a pretty good IT background so it hasn't bugged me much, but it has severely hurt others and caused a lot of sub-75s. Keep in mind on the Ninja videos that they are a few years older now, and tech changes literally everyday.
