Hi there, I passed on first tries for my exams using only Becker. I think the key is truly understand MCQs after going through the materials. Honestly, I don't know how Ninja is different from Becker, but I would imagine the knowledge applied would be the same? If you have capacity after hammering Becker MCQs multiple times, it's not a bad idea to get some new questions. Until then, it should be sufficient to focus on one material.
Shoot for the stars!
