A practical 4-week OAR rhythm looks like this:

• Week 1: Diagnose weak areas with mixed math, reading, and mechanical sets
• Week 2: Drill your weakest one or two topics every day
• Week 3: Add timed mixed blocks and error review
• Week 4: Simulate realistic pacing and clean up recurring mistakes

Use a notebook or spreadsheet to tag misses as one of four types:

1. Concept gap
2. Formula / fact recall gap
3. Reading or interpretation error
4. Rushing / process error

That simple classification tells you whether to re-study content, memorize a rule, slow down, or change your scratch-work habits.
