24.2 Last-Week Review Map
Key Takeaways
- Spend the final week consolidating high-yield COA domains, not opening new textbooks.
- Lead with your weakest heavily tested areas: ocular anatomy, instrument procedures, lensometry/optics, and pharmacology.
- Use short mixed-domain sets so you practice switching topics the way the real exam shuffles them.
- The day before, rehearse formulas, normal values, and logistics, then stop and rest.
24.2 Last-Week Review Map
The last week is consolidation, not new learning. Anchor your plan to the IJCAHPO COA content areas, which span ocular anatomy and physiology, visual assessment, pupil and motility evaluation, tonometry, lensometry and basic optics, refractometry support, ophthalmic pharmacology, microbiology and aseptic technique, ophthalmic imaging support, patient services and history-taking, and minor surgical and clinic assisting. Your error log tells you which of these is weakest for you.
High-yield normal values to memorize cold
The exam reliably tests a handful of reference numbers. Lock these in by mid-week:
| Parameter | Normal / reference value |
|---|---|
| Intraocular pressure (IOP) | 10-21 mmHg |
| Central corneal thickness | ~540-560 microns |
| Anterior chamber depth | ~3.0 mm |
| Normal pupil size (room light) | 2-4 mm |
| Vertex distance (spectacle) | ~12-14 mm |
| Prism conversion | 1 prism diopter ≈ 0.57 degrees |
| Snellen denominator at 20/20 | letter subtends 5 arcmin at 20 ft |
| Goldmann tonometry calibration check | drum settings 0, 2, 6 g |
If you cannot recall a value, you cannot reason through the question that depends on it.
A day-by-day map
| Days out | Focus | Action |
|---|---|---|
| Day 7-5 | Weakest high-yield domains | Re-read the IJCAHPO outline section, then drill a 25-item set; write one rule per miss |
| Day 4-3 | Mixed timed sets | 50-item shuffled sets under the clock to practice domain switching |
| Day 2 | Error-log rules + normal values | Recite the value table; review only your highest-frequency error rules |
| Day 1 | Logistics and light review | Confirm Pearson VUE appointment, ID, route; skim notes; sleep early |
Why mixed sets matter
The live exam does not label questions by domain or group them by topic. If you only ever drill one domain at a time, you train recall but not the cognitive switching the exam demands. From Day 4, every practice set should shuffle anatomy, optics, pharmacology, and procedure items together so a tonometry question can follow a microbiology question without throwing you off.
Stop-adding-resources rule
A common failure mode in the final week is collecting new study apps, new question banks, and new video playlists. Each new resource resets your sense of progress and surfaces unfamiliar phrasings that breed last-minute doubt. The rule: after Day 5, no new resources unless a specific repeated miss has no explanation in your current materials. Depth on what you already know beats shallow exposure to something new.
Prioritize by weight times weakness
Do not spend the final week perfecting a domain you already score 90% on. Rank each content area by test weight multiplied by your error rate and attack the top of that list first. A moderately weighted domain where you miss half the items will move your score far more than a heavily weighted domain you already nearly master.
- Day 7-5: weakest high-yield domains, 25-item drills.
- Day 4-3: 50-item mixed, timed sets.
- Day 2: normal-value table plus top error rules.
- Day 1: logistics, light skim, early sleep.
- After Day 5: freeze new resources.
Common trap
Candidates often "review" by re-reading notes passively. Passive reading feels productive but does not test retrieval. Replace it with active recall: cover the value, state it aloud, then check. The exam rewards retrieval, not recognition.
High-yield concept clusters to lock down last
Beyond raw numbers, a handful of relationships generate many questions. Reviewing them as clusters is more efficient than as isolated facts.
- Pupil pathways: Distinguish a relative afferent pupillary defect (RAPD, the swinging-flashlight test indicating optic nerve or retinal disease) from anisocoria causes such as Horner syndrome (miosis worse in dark) versus a third-nerve palsy or pharmacologic mydriasis (worse in light). Know which testing condition exaggerates each.
- Tonometry technique: Goldmann applanation is the reference standard; the semicircles (mires) should overlap with their inner edges just touching. Excess fluorescein widens the mires and falsely raises the reading; too little narrows them. Calibration is checked at drum settings 0, 2, and 6.
- Sterilization versus disinfection: Autoclaving (steam under pressure) sterilizes instruments; tonometer tips are typically disinfected. Know that asepsis prevents endophthalmitis and that the order matters in clinic workflow.
- Pharmacology cues: Mydriatics (tropicamide, phenylephrine) dilate; cycloplegics (cyclopentolate, atropine) paralyze accommodation; miotics (pilocarpine) constrict. A question that mentions cataract surgery prep points to dilation; one mentioning a young hyperope's cycloplegic refraction points to cyclopentolate.
Sleep and logistics are part of the score
Research on testing performance is consistent: a full night of sleep before the exam outperforms a final cramming session. The night before should end with logistics confirmed (route, ID, appointment time) and notes closed by early evening. Walking into a 180-minute exam fatigued degrades exactly the sustained attention the back third of the test demands. Treat rest, hydration, and a familiar light meal as deliberate score-protection steps, not afterthoughts, and resist the urge to drill one more 50-item set at midnight.
A rested brain recalls a normal value in seconds that a tired brain stalls on for a minute, and across 200 questions those saved seconds are exactly the buffer that protects your back third.
It is five days before your COA exam. You consistently score 92% on ocular anatomy (heavily tested) but 55% on lensometry and optics (moderately tested). Where should the final week's effort go first?
