Question 1
A researcher observes that a population of rabbits in a forest increases rapidly after a wolf population declines. What is the most logical scientific conclusion?
Correct Answer:
The rabbits have lost their primary predator, increasing their survival rate.
Explanation:
Wolves are predators of rabbits. Without them, the rabbit population experiences less predation and grows.
Question 2
An experiment tests the effect of sunlight on plant growth. Group A gets 12 hours of light, Group B gets 6 hours, and Group C gets 0 hours. What is the independent variable?
Correct Answer:
The amount of sunlight.
Explanation:
The independent variable is the one being manipulated by the researcher, which is the amount of sunlight.
Question 3
A scientist notes a correlation between high sugar intake and heart disease. Can she conclude that sugar causes heart disease based only on this?
Correct Answer:
No, correlation does not imply causation without controlled experiments.
Explanation:
A correlation simply means two variables trend together; it does not prove one causes the other.
Question 4
A geneticist crosses a red flower (RR) with a white flower (WW) and all offspring are pink (RW). What type of inheritance is this?
Correct Answer:
Incomplete dominance
Explanation:
Incomplete dominance occurs when the phenotype of the offspring is a blend of the parents' traits.
Question 5
A cell is placed in a hypertonic solution. Water leaves the cell, causing it to shrink. What is this process called?
Correct Answer:
Osmosis
Explanation:
Osmosis is the diffusion of water across a semipermeable membrane from an area of low solute concentration to high solute concentration.

About this Exam

The NLN Pre-Admission Examination (PAX) is a standardized entrance test developed by the National League for Nursing.

It is designed for aspiring nursing students seeking admission to various registered nursing (RN) and licensed practical nursing (LPN/LVN) programs across the United States.

This exam serves as a crucial metric for nursing schools to evaluate the academic readiness of applicants in foundational subject areas.

Successfully passing the PAX is often the first major step toward securing a spot in a competitive nursing program.

What the Course Entails and Exam Details

The PAX is not a single course, but a comprehensive examination that tests knowledge and skills acquired throughout your secondary education.

The syllabus is divided into three primary subject areas:

  • Verbal Ability: This section measures reading comprehension and word knowledge through vocabulary and analogies.
  • Mathematics: Candidates are tested on their ability to perform basic computational skills, including arithmetic, algebra, geometry, conversions, and interpreting graphs.
  • Science: This extensive section covers high school-level knowledge in general biology, chemistry, physics, and human anatomy and physiology.

The primary goal of the exam is to ensure candidates possess the scientific literacy and computational speed necessary for the rigorous nursing curriculum.

 

What to Expect in the Final Exam

The NLN PAX is a rigorous computer-based exam.

You can expect the following structure when sitting for the final test:

  • Format: The exam consists entirely of multiple-choice questions.
  • Number of Questions: There are typically 160 questions in total, though some may be unscored pre-test questions.
  • Time Limit: The total time allowed is approximately 2 hours and 5 minutes, usually allocated as 60 minutes for the Verbal section, and 65 minutes combined for Mathematics and Science.
  • Passing Score: There is no universal raw passing score; the NLN provides a composite percentile score. Most nursing programs require candidates to score at or above the 50th percentile, though competitive programs may require higher scores.
  • Rules: No calculators are permitted during the Mathematics section; scratch paper is provided.

 

 How to Study and Exam Centers

Preparation is the absolute key to success on the PAX.

Follow these actionable strategies:

  • Take a Diagnostic Practice Test: Begin by taking a FREE PAX Practice Test 2026 Official Study Guide [PDF]. This will identify your weak areas immediately.
  • Focus on Science Vocabulary: The science section is vast, so focus on key terminology in anatomy, physiology, and chemistry.
  • Review Math without a Calculator: Practice basic calculations, fractions, decimals, and algebraic equations by hand.
  • Simulate the Time Constraints: When taking full-length practice exams, adhere strictly to the time limits to build your testing stamina.

Where to Take the Exam:

The NLN PAX is administered through the NLN Testing Services portal.

Candidates typically take the exam at specific physical testing centers at the college or university to which they are applying, through an authorized ProctorU online remote proctoring session, or at designated independent testing centers.

Always check the specific registration requirements of your target nursing program.

 

Job Opportunities from the Course
