NPLEX II study plan

NPLEX II · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Part I – Biomedical Science

  • Map every Part I biomedical topic to a one-page outline, flagging biochemistry, physiology, and pathology as highest-yield for naturopathic clinical reasoning

  • Build a spaced-repetition deck of 150 foundational cards covering enzyme kinetics, cofactors, and rate-limiting steps in major metabolic pathways

  • Draw the full glycolysis, TCA cycle, and oxidative phosphorylation maps from memory twice, correcting errors from a reference text

  • Write a 300-word summary linking mitochondrial dysfunction to fatigue and chronic disease presentations you expect to see in practice

Your checkpoint

Completed Part I topic map plus a 150-card deck with at least 90 percent of cards tagged by organ system

Week 2

Part I – Biomedical Science

  • Trace autonomic and neuroendocrine pathways from hypothalamus through target organ, writing each pathway once without notes

  • Compare innate versus adaptive immunity step by step and predict the lab pattern for each of four common immunodeficiency scenarios

  • Explain acid-base compensation using four worked arterial blood gas cases, deriving the expected direction and magnitude of change

  • Annotate a one-page diagram of the renin-angiotensin-aldosterone and hypothalamic-pituitary-adrenal axes with the clinical consequence of each block

Your checkpoint

Four fully worked ABG cases with correct primary disorder, compensation, and anion gap interpretation

Week 3

Part I – Biomedical Science

  • Classify 40 high-frequency pathogens by Gram stain, oxygen requirement, and classic syndrome, then self-quiz to 85 percent recall

  • Summarize mechanisms of action and key adverse effects for the major antimicrobial and antifungal classes in a comparison table

  • Describe the pathophysiology of neoplastic transformation and list the tumor markers and screening logic for five common cancers

  • Predict the expected electrolyte and hematologic derangement for six common drug classes without referencing notes

Your checkpoint

Pathogen and drug comparison table covering at least 40 organisms and 15 drug classes, self-quizzed to 85 percent recall

Week 4

Part I – Biomedical Science & Part II – Core Clinical Science

  • Convert each Part I system outline into a clinical correlation sheet linking mechanism to presentation, diagnosis, and treatment principle

  • Rank all Part I topics by personal error rate and allocate remaining review time to the top five weakest areas

  • Complete 60 mixed Part I practice items under timed conditions and log every miss by mechanism rather than by topic name

Your checkpoint

Clinical correlation sheet for all major organ systems plus a remediation list of the five weakest Part I areas

Week 5

Part II – Core Clinical Science

  • Write a structured history and physical framework for each major chief complaint, including red flags that mandate referral

  • Build a differential diagnosis tree for chest pain, abdominal pain, headache, and fatigue with discriminating findings at each branch

  • Interpret 20 common laboratory and imaging patterns, stating the next best diagnostic step for each

  • Practice three 10-minute case vignettes aloud, verbalizing the reasoning chain from chief complaint to working diagnosis

Your checkpoint

Differential diagnosis trees for four chief complaints with at least six branches each and red flags annotated

Week 6

Part II – Core Clinical Science

  • Outline the diagnostic criteria and first-line management principles for 25 high-yield conditions across cardiovascular, endocrine, and gastrointestinal systems

  • Explain the therapeutic rationale for at least 15 commonly used botanicals and nutrients, mapping each to a specific mechanism and a safety caution

  • Identify drug-herb interaction risks for 10 common prescription classes and state the clinical action for each

  • Draft a patient education handout for one chronic condition that integrates lifestyle, nutrition, and botanical considerations

Your checkpoint

25-condition management outline plus a completed patient education handout reviewed against safety cautions

Week 7

Part II – Core Clinical Science & Part I – Biomedical Science

  • Complete two timed 100-item mixed practice blocks simulating exam pacing and record score by domain to identify drift

  • Review every missed item from week 7 and week 4, writing the underlying principle rather than the answer

  • Rehearse clinical decision-making on 10 ethical and practice-management scenarios, stating the governing principle and action

  • Drill the 100 highest-yield facts across both domains until recall is above 90 percent on two consecutive passes

Your checkpoint

Two timed practice block score reports with a written remediation log of every missed item

Week 8

Part I – Biomedical Science & Part II – Core Clinical Science

  • Run a final error audit, grouping remaining weak areas into no more than five themes for targeted review

  • Complete one full-length timed simulation and analyze pacing, fatigue, and question-stem misreads

  • Recite the core mechanism for each major disease category from memory in a 45-minute self-review

  • Finalize a one-page pre-exam reference sheet limited to facts you have repeatedly missed

Your checkpoint

Full-length simulation score with a one-page pre-exam reference sheet and a five-theme final review list

Milestones

Week 4: Score at least 65 percent on a 60-item timed Part I block and have clinical correlation sheets completed for all major organ systems

Week 6: Correctly verbalize the reasoning chain for three of four practice case vignettes without notes and complete the 25-condition management outline

Week 8: Score at least 75 percent on a full-length timed simulation with balanced performance across both domains and no single theme accounting for more than a third of misses
