Scaled score 555 is the passing line — what mock exam score is safe?

Short Answer

ARDMS hasn't published exactly how the exam is scored. Based on patterns test-takers have noticed, it seems that easy questions almost everyone gets right don't add much weight, while harder questions many people miss seem to count for more when you get them right — and being notably weak in one specific content area appears to pull your overall score down, while scoring evenly across all areas tends to produce a higher result. But since none of this is officially confirmed, no specific mock score — URR or otherwise — reliably converts into a "safe" number above 555.
