How to use this guide
How to study for the HESI A2
Use your nursing program's required HESI A2 sections first, then build across math, reading, vocabulary, grammar, biology, chemistry, anatomy, and physiology so no academic subject is a weak link.
Identify the subject skill
Decide whether the item is testing calculation, passage evidence, word meaning, grammar, biology, chemistry, or A&P.
Use the exact prompt source
For math, preserve units; for reading, use the passage; for science and English, use the concept being tested rather than outside assumptions.
Eliminate common traps
Remove answers with wrong units, unsupported reading claims, imprecise vocabulary, grammar changes that alter meaning, or science terms at the wrong level.
Tie mistakes to remediation
After each set, label the missed skill so your next drill targets the subject area the score report or program requirement cares about.
Arithmetic, Fractions, Decimals, Ratios, Percentages, and Conversions
Math questions test arithmetic accuracy, fractions, decimals, percentages, ratios, proportions, unit conversions, and practical nursing-school word problem setup.
Key rules
Rule 1
Arithmetic, Fractions, Decimals, Ratios, Percentages, and Conversions questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Rule 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Rule 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Common traps
Treating related standards as interchangeable without checking the source.
Prevention: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Prevention: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Prevention: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Fraction
A fraction compares a part to a whole and can be converted to a decimal or percentage.
Decimal
A decimal uses place value and must be aligned correctly in calculation.
Percentage
A percentage means per hundred and is often converted to a decimal for calculation.
Ratio
A ratio compares quantities and should keep the same unit basis.
Proportion
A proportion states that two ratios are equal and can solve for an unknown.
Unit Conversion
Unit conversion changes labels while preserving the same amount.
Word Problem
A word problem should be translated into quantities, units, and the requested unknown.
Estimate Check
Estimate checks catch misplaced decimals, impossible units, and operation errors.

FAQ
Common HESI A2 questions
Is this the official HESI A2?
No. These are original practice questions aligned to public Elsevier HESI A2 study and testing guidance. They are not copied from secure HESI exam forms.
How many subjects are on the HESI A2?
HESI A2 is modular and school configured. Elsevier's current Admission Assessment review covers math, reading comprehension, vocabulary, grammar, biology, chemistry, and anatomy and physiology.
Why does this mock have 175 questions?
There is not one universal HESI A2 exam length for all schools. This mock uses 25 questions per current academic review subject so candidates can practice a full balanced academic set.
Should I study every section?
Verify your program's required HESI A2 topics first. Then use the broader bank to strengthen adjacent academic skills, especially if applying to multiple programs.
How should I use the 601 questions?
Start with your required math, reading, vocabulary, grammar, and A&P sections, then rotate biology and chemistry if your school requires them or if your science foundation needs review.
