On my first exam, I thought I was well prepared and had Ninja MCQ score of around 75% Roger CPA MCQ of 80%. However, I did not score anywhere near the passing percentage.
However, after discovering that researching authoritative literature may help on TBS, I did that on my second exam (4 weeks after first one but I had 3 weeks to re-study it as I thought I passed it and was studying on another section) I got “Strong” on TBS!!! I got “Weaker” on TBS on my first try.
But you should still know the material inside and out — literally!!
Know and be familiarize with the authoritative literature. While you're at it, try to relate MCQ questions with authoritative literature. Authoritative literature is the source of what we're learning after all.
