Build an 8–12 week calendar weighted toward interventions (the largest OTR domain).
03
Practice multi-select scenario sets: three of six options are correct; partial strategy matters.

Apply when you can schedule inside the application validity window (commonly 90 days).
FAQ
What score do I need on NBCOT?
OTR passing standard is a scaled 450. Raw percent correct is not published and varies by form.
How do I make an NBCOT study schedule?
Work backward from your test date in weekly blocks: eval, planning, interventions, practice management, then mixed timed sets. Keep an error log by domain, not by textbook chapter.
