How to practise

Nln Nursing Exam

Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026

Short answer

The NLN nursing exam most candidates sit is the PAX, the National League for Nursing Pre-Admission Examination, covering verbal ability, mathematics and science. Practice questions are the fastest way to prepare, but only if you run them as timed sessions, review every wrong answer for its cause, and track composite scores across weeks rather than trusting a single good day.

Why practice questions beat re-reading

The PAX tests three things: reading and vocabulary, arithmetic and algebra, and a broad sweep of biology, chemistry, physics and earth science. Re-reading a science textbook feels productive because the material is familiar. Familiarity is the trap. Recognising a paragraph on osmosis is not the same as answering a question that asks which way water moves across a membrane when the solute concentrations are given.

Practice questions force retrieval, and retrieval is what the exam measures. They also reveal the specific shape of NLN items. The verbal section leans on vocabulary in context and short reading passages. The maths section is dominated by fractions, decimals, percentages, ratios and unit conversions, which are exactly the skills that later become drug calculations. The science section rewards breadth over depth. You cannot learn that distribution from a textbook chapter list. You learn it by sitting a set, seeing which sections bleed time, and adjusting.

There is a second reason. The PAX is timed, and candidates who have never worked under the clock lose marks they could have earned. Practice under time exposes that before the real sitting does.

Structuring a session

Run each session as one section of the exam, not a random mix. Pick verbal, maths or science, set a timer that matches the pace of the real section, and work without notes. Mixing the three in one sitting hides where your time actually goes.

For maths, aim for a block of around thirty questions and note the time at which you finish. If you run over, the problem is usually not knowledge but method: long division by hand, converting a fraction to a decimal the slow way, or re-reading a word problem three times. For verbal, work the vocabulary items first and the reading passages second, since passages are where time disappears. For science, accept that you will meet questions on topics you never studied. Answer, flag, move on. The exam does not penalise guessing, so a blank is always the wrong choice.

Two or three sessions a week, each of forty to sixty minutes, beats a single weekend marathon. The gap between sessions is when forgetting happens and re-learning sticks. In the last fortnight before the sitting, run at least one full-length timed practice exam across all three sections in a single sitting.

Reviewing the ones you got wrong

Review takes longer than the set itself, and that is the point. For every wrong answer, write down why it was wrong in one of four categories: did not know the content, knew it but misread the question, knew it but ran out of time, or guessed and the guess failed. The category tells you what to fix.

Content gaps go on a list. On the PAX science section that list is often long and scattered: the stages of mitosis, the pH scale, Newton's laws, the parts of a cell, the function of the loop of Henle. Do not try to relearn whole subjects. Learn the specific fact that the question tested, then look at the two or three facts around it. Misreads are a discipline problem, and the fix is to underline what the question is asking before reading the options. Time losses are a method problem, and the fix is to practise the slow skill in isolation, usually a type of calculation.

Review the questions you got right by guessing with the same care. A lucky guess is a wrong answer that has not happened yet.

Tracking whether it is working

Keep a simple log: date, section, number of questions, score as a percentage, and time taken. One line per session. After three weeks you have a trend, and the trend is the only honest signal. A single score of 85 percent on a science set tells you very little, because science sets vary wildly in topic. Five science sets averaging 78 percent, up from 64 percent a month earlier, tells you the method is working.

Watch two things beyond the raw score. The first is time. If your maths percentage is flat but you are finishing the block five minutes faster, you are improving, because that time will be spent on the harder questions in the real exam. The second is the error categories from your review. Early on, most wrong answers should be content gaps. If misreads and time losses still dominate after a month, the knowledge is there and the exam technique is not.

Programmes set their own cut-off scores for the PAX, and some weight the composite differently from the section scores. Find out what your target programme requires before deciding when you are ready.

Try a set

The practice sets on this site are built to be run the way this page describes: one section at a time, timed, with an explanation for every option rather than just the correct one. Start with a maths block, because it is the section where the fastest gains are made and the skills carry straight into nursing school drug calculations.

Score it, log it, and do the review before you open a second set. If you have never sat a PAX-style exam before, resist the urge to read all the explanations for questions you got right. Read the ones you got wrong and the ones you guessed. Then come back in two days, not two hours, and run a verbal or science block. Three weeks of that rhythm will tell you where you stand far more accurately than any single mock.

The next step on this is the same as on everything else here: answer questions and read the rationales. Our fundamentals practice questions are the closest set to what this page covers.

Common questions

What is on the NLN PAX exam?

Three sections: verbal ability, mathematics and science. Verbal covers vocabulary and reading comprehension. Mathematics covers arithmetic, fractions, decimals, percentages, ratios, basic algebra and conversions. Science samples biology, chemistry, physics and earth science at a general level.

Is there a penalty for wrong answers on the NLN exam?

No. The score is based on correct answers, so leave nothing blank. If time is running out, answer every remaining question rather than leaving a gap.

What score do I need on the NLN PAX?

There is no single national pass mark. Each nursing programme sets its own minimum, and some look at the composite while others require a threshold in each section. Check the admissions page of the programme you are applying to.

How long should I study for the NLN nursing exam?

Most candidates need four to eight weeks of regular practice sessions, with the science section usually taking longest because it is so broad. Start with a timed diagnostic set in each section, then let your weakest section decide how you spend the time.
