Feel like I am plateauing in my prep.

I have been reviewing and practicing for the test for about a month in earnest now. My test date is March 27. I have been drilling the mindset (I reread aloud the 50 AR principles before every study session) and taking careful note of the questions I am getting wrong and why.

My performance on practices has improved somewhat. I have gotten more solid with predictive and much more confident with agile. However my performance is still in the 65-75% range, occasionally into the 80's but rarely. The mindset has helped but I don't feel like I am continuously improving.

I'm not sure what I should prioritize in order to get steadily in 75-85% territory. Should I practice the mindset more? Continue drilling questions? Go back, review material, take a break from practice? Move my test date?
