I can't answer whether or not it will push you over as I have yet to sit- however I am finding them VERY HELPFUL in supplementing / streamlining my own notes. BEC (at least to me) has proven to be a monster with so much random information. I have found the Ninja Notes more helpful for BEC than I have for any other section- they have really helped me condense my notes and focus in on the main points. Have found them especially good for econ. and IT so personally I recommend.
