Becker vs. NINJA REG Advice

I test for REG on the 24th and I'm just about finished the entirety of the Becker material. I've completed all of the course content (MCQs, SIMS, lectures, flashcards, etc.), and received a 57% on my first practice exam. To help bump my score up on the next practice exam attempt, I wanted to supplement my learning with NINJA so I don't study the same Becker questions on repeat. However, I'm noticing NINJA is sometimes focused on areas not covered or barely emphasized in Becker. This is causing me to become frustrated and now I'm not sure what areas to focus on and how to study efficiently.

Does anyone else feel this way or can provide some insight? Looking for the best path forward. Thanks!!
