PA-CN practice questions - frequently asked questions

Plain answers about how PA-CN Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real PA-CN exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The PA-CN exam spans 11 domains: Chronic Kidney Disease (20% of the exam); Glomerular Disorders (6% of the exam); Tubulointerstitial/Viral Disorders (5% of the exam); Vascular Disorders (3% of the exam); Systemic Disorders (6% of the exam); Kidney Transplantation (5% of the exam); Hypertension (10% of the exam); Renal Pathophysiology (14% of the exam); Acute Kidney Injury/Intensive Care Unit Nephrology (11% of the exam); End-Stage Renal Disease / Dialysis (17% of the exam); Legal/Ethical Issues and Emerging Topics (3% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Chronic Kidney Disease 20%; End-Stage Renal Disease / Dialysis 17%; Renal Pathophysiology 14%; Acute Kidney Injury/Intensive Care Unit Nephrology 11%; Hypertension 10%; Glomerular Disorders 6%; Systemic Disorders 6%; Tubulointerstitial/Viral Disorders 5%; Kidney Transplantation 5%; Vascular Disorders 3%; Legal/Ethical Issues and Emerging Topics 3%.

The PA-CN exam has 120 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
