Week 220-24 hours this week
- Work through structural diagnosis by region, then the direct and indirect technique families
- Drill viscerosomatic reflex levels and Chapman point locations until recall is automatic
- Memorise the absolute and relative contraindications for high velocity low amplitude technique
- Complete an OMM-focused question set from TrueLearn COMBANK or COMQUEST, since this domain carries a published 10 percent minimum on Level 2-CE
- Review Savarese OMT Review or your school's equivalent text for technique indications
Musculoskeletal presentations
Week 324-28 hours this week
- Cover rheumatology, orthopaedics and sports medicine, the largest Dimension 2 category at a 13 percent minimum
- Link each musculoskeletal presentation to the manipulative treatment that would be appropriate or contraindicated
- Drill imaging selection for back pain, joint pain and fracture presentations

Circulatory, hematologic and respiratory systems
Week 424-28 hours this week
- Work cardiology and pulmonology question blocks covering the two 10 percent minimum categories
- Drill ECG interpretation and chest imaging pattern recognition, since audiovisual exhibits appear on the exam
- Review anticoagulation decisions, anaemia workup and transfusion reactions
- Practise linking rib and thoracic somatic dysfunction to respiratory presentations
Gastrointestinal, nutritional health and endocrine
Week 524-28 hours this week
- Cover gastrointestinal and nutritional health at a 10 percent minimum plus endocrine and metabolism at 5 percent
- Work diabetes management, thyroid disorders and adrenal presentations
- Review gastrointestinal bleeding, liver disease and pancreatitis pathways
- Complete a timed mixed block and review every incorrect answer against the competency domain it maps to
Nervous system, mental health and integumentary
Week 624-28 hours this week

Genitourinary, renal, breasts, reproduction and human development

- Cover renal and genitourinary presentations alongside breast disease at the 5 percent minimum
- Work obstetrics, gynaecology and paediatric development under human development, reproduction and sexuality
- Drill electrolyte and acid base disorders as clinical vignettes rather than isolated calculations
- Review screening schedules across the lifespan, which cross into the community health category
Community health, wellness and systems-based practice
Week 820-24 hours this week
- Cover community health and patient presentations related to wellness, the second largest Dimension 2 category at a 12 percent minimum
- Work preventive care, immunisation schedules and screening guideline questions

- Drill professionalism and ethics vignettes, which carry a 7 percent minimum on Level 2-CE
Biostatistics, literature interpretation and communication
Week 920-24 hours this week
- Work every biostatistics question in your bank, covering study design, bias and the calculation set
- Practise applying a published trial result to an individual patient, the core of practice-based learning and improvement
- Drill communication vignettes on breaking bad news, shared decision making and handoffs
- Sit a second COMSAE self-assessment to measure movement against the passing standard
Full-length simulation and pacing
Week 1026-30 hours this week
- Sit a full 320 question simulation split into two four-hour sessions of four 40-question sections
- Rehearse spending your 60-minute pooled break across the seven scheduled break points rather than exhausting it early
- Practise the review screen workflow inside each section, since NBOME states that time spent reviewing questions or adding comments counts toward your total testing time
- Review the NBOME sample questions to confirm you can use the highlight, strikeout and calculator tools without hesitation
Weak domain repair
Week 1124-28 hours this week
- Rebuild the two weakest competency domains from your COMSAE Performance Profile with fresh question blocks
- Redo previously missed OMM questions, since that domain is the one most candidates leave until last
- Rewrite your viscerosomatic reflex and technique contraindication sheets from memory and check them
- Sit a final COMSAE self-assessment under full timing
Consolidation and exam day logistics
Week 1216-20 hours this week
