1.2 Study Strategy, Calculator Use & Test-Day Pacing

How to Study: A 3–6 Week Plan

Give yourself 3–6 weeks of focused review before your test date. Less than three weeks is rushed for the breadth of content; more than six weeks and you risk forgetting early material unless you spiral back. The plan below assumes about 5–7 hours per week.

Prioritize Measurement. At 35% of the section and the most common source of unit-conversion traps, it gives you the most points per hour of study. Second, drill fractions, decimals, and percents — they appear inside almost every other content area. Third, practice setting up ratios and proportions for dosage-style word problems; the arithmetic is usually simple, but the setup is where points are lost.

Calculator Discipline

A calculator is permitted, so the question is not can you use it but when you should. Treat the calculator as a check, not a crutch.

1. Estimate first. Before you touch the calculator, round the numbers and estimate the answer in your head. If the calculator then returns something off by a factor of 10, you know immediately there is a decimal or unit error.
2. Use it for tedious arithmetic, not simple arithmetic. Reaching for the calculator on 25 + 25 wastes time you need for word problems. Use it for multi-digit multiplication, long division, and conversions with ugly decimals.
3. Don't use it to decide the operation. The calculator does not tell you whether the problem is multiplication or division — you decide that, then compute.
4. Watch units. A calculator happily computes 5 kg × 2.2 lb/kg, but if you typed 5 × 2.2 and forgot the units, you may not notice you answered in pounds when the question asked for kilograms.

Test-Day Pacing

You have 60 minutes for 45 items — about 1.3 minutes per item. Some items (direct computation) will take 30 seconds; others (multi-step word problems with a unit conversion) will take 2–3 minutes. The pacing strategy below keeps you on track.

The single most important pacing rule: never sink more than about 2 minutes on one item before flagging and moving on. A hard item is worth exactly 1 point — the same as an easy item. Bank the easy points first, then come back.

No Guessing Penalty — Never Leave Blank

There is no penalty for guessing. Unanswered items are scored as incorrect, same as a wrong answer. Therefore the expected value of guessing is always positive: with four choices, a random guess is worth 0.25 on average, a blank is worth 0. When you return to flagged items at the end:

1. Eliminate one or two clearly wrong answers if you can — this raises your guess value from 0.25 to 0.33 or 0.50.
2. Pick an answer for every item. Even a blind guess beats a blank.
3. Do not change a confident answer unless you find a concrete error in your reasoning.

Target the Percentile Your Program Wants

Because there is no national passing score, your target is program-specific. Before test day:

• Look up the NEX math percentile cut score for every nursing program you are applying to.
• If a program publishes a composite requirement, confirm how it weights NEX math.
• Set your personal target above the program's cut score — aim for a buffer of at least 10 percentile points so a bad day still clears the bar.

Common Traps to Drill

These are the recurring ways NEX math items are missed — drill each one specifically:

• Unit mismatches. The stem gives kilograms and the answer choices are in pounds, or the conversion is in a direction you did not expect. Always confirm the requested unit before computing.
• Decimal-point errors. Off-by-10, off-by-100 from a slipped decimal. Your estimate catches this.
• Misreading 'percent of.' "What is 30% of 80" is multiplication; "30 is what percent of 80" is a proportion. Read the stem for which is which.
• Order of operations. Parentheses, then exponents, then multiplication/division, then addition/subtraction. The calculator follows order of operations automatically; you must still set up the expression correctly.
• Sign errors with integers. Subtracting a negative is adding; multiplying two negatives is positive. Write the sign explicitly.

The Day Before and Day Of

• Day before: light review only, no new material. Skim your error log. Sleep.
• Day of: bring permitted ID, arrive early (or for virtual, log in 15 minutes early and close other apps), have scratch paper and pen/pencil if your delivery allows it.
• During the exam: estimate, compute, check, answer, move on. Use every minute — if you finish early, return to flagged items and recheck units.
