For many students, the Math section is the most intimidating part of the HESI A2 exam.
The moment they see fractions, percentages, ratios, and conversions, anxiety starts to build.
The good news?
HESI A2 Math is one of the most predictable sections on the entire exam.
Unlike some subjects that require extensive memorization, Math follows patterns. Once you understand those patterns and practice enough questions, your score can improve dramatically.
In fact, many students who initially struggle with Math discover that it becomes one of their strongest sections after a few weeks of focused preparation.
In this guide, you’ll learn practical HESI A2 Math tips that can help you improve accuracy, increase speed, and walk into the exam with confidence.
Why Students Struggle With HESI A2 Math
Most students don’t fail Math because the questions are too difficult.
They struggle because:
- They haven’t practiced in years
- They rush through word problems
- They forget basic formulas
- They rely too heavily on calculators
- They don’t understand common question patterns
The good news is that every one of these problems can be fixed.
Tip 1: Learn What Topics Are Tested Most Often
Before you start studying, know where to focus.
The most commonly tested HESI A2 Math topics include:
- Fractions
- Decimals
- Percentages
- Ratios
- Proportions
- Conversions
- Basic algebra
- Word problems
These topics should receive most of your study time.
Tip 2: Master Fractions First
Fractions appear everywhere.
You’ll often need to:
- Add fractions
- Subtract fractions
- Multiply fractions
- Divide fractions
- Convert fractions to decimals
Students who are comfortable with fractions usually find the rest of the Math section much easier.
Tip 3: Stop Memorizing and Start Understanding
Many students try to memorize procedures without understanding why they work.
For example, instead of memorizing how to solve proportions, learn what a proportion actually represents.
Understanding concepts makes it easier to solve unfamiliar questions.
Tip 4: Learn Common Conversion Factors
Conversions are among the highest-yield topics on the HESI A2.
You should know:
- 1 kilogram = 1000 grams
- 1 liter = 1000 milliliters
- 1 pound = 16 ounces
- 1 foot = 12 inches
These appear frequently and are often easy points when prepared properly.
Tip 5: Practice Ratios Every Day
Ratios and proportions are nursing-school favorites.
Example:
If 3 pens cost $6, how much will 8 pens cost?
Questions like these appear regularly.
The more you practice them, the faster they become.
Tip 6: Read Word Problems Twice
Many mistakes happen because students rush.
Before solving:
- Read the question once
- Read it again carefully
- Identify exactly what is being asked
This simple habit prevents careless errors.
Tip 7: Write Down Important Information
When solving word problems:
- Write numbers down
- Label units
- Organize information
This helps reduce confusion and improves accuracy.
Tip 8: Learn Percentage Shortcuts
Percentage questions often appear in predictable forms.
Examples:
- Finding a percentage of a number
- Percentage increase
- Percentage decrease
The more examples you solve, the easier these become.
Tip 9: Focus on Accuracy Before Speed
Students often try to work quickly too early.
That’s a mistake.
First:
- Learn the process
- Improve accuracy
Speed comes naturally with practice.
Tip 10: Take a Diagnostic Math Test
One of the smartest things you can do is identify weaknesses immediately.
A free HESI A2 Math Practice Test can show you:
- Which topics need work
- Which topics you’re already strong in
- Where to focus your study time
This prevents wasting hours on areas you’ve already mastered.
Tip 11: Review Every Wrong Answer
Getting a question wrong is valuable.
Each mistake reveals a weakness.
Ask:
- Why was my answer incorrect?
- What concept did I miss?
- How can I avoid this next time?
This is where real improvement happens.
Tip 12: Learn Basic Algebra
The HESI A2 does not require advanced algebra.
However, you should be comfortable solving simple equations.
Example:
2x + 8 = 20
Understanding basic algebra can earn easy points.
Tip 13: Practice Mental Math
While calculators are generally available during the Math section, basic mental math is still useful.
For example:
- 50% of 80
- 25% of 100
- 10% of 200
These should become automatic.
Tip 14: Create a Formula Sheet
Keep a list of:
- Conversion factors
- Percentage formulas
- Fraction rules
- Ratio setups
Reviewing this regularly improves retention.
Tip 15: Study a Little Every Day
Math skills improve through repetition.
Even 20 to 30 minutes daily can make a noticeable difference.
Consistency matters more than marathon study sessions.
Tip 16: Practice Under Timed Conditions
Many students know the material but struggle under pressure.
Simulating exam conditions helps build confidence and speed.
Try:
- Setting a timer
- Completing practice questions without interruptions
- Tracking your progress
Tip 17: Use High-Quality Study Materials
Random online questions often vary in quality.
Look for resources specifically designed for the HESI A2.
A dedicated HESI A2 Math Study Guide can help you focus on:
- Frequently tested topics
- Realistic question styles
- Step-by-step solutions
This makes studying more efficient.
Tip 18: Learn From Patterns
After enough practice, you’ll notice the same types of questions appearing repeatedly.
For example:
- Conversion questions often follow similar formats
- Ratio questions usually require the same setup
- Percentage questions use familiar patterns
Recognizing these patterns can dramatically improve speed.
Tip 19: Don’t Ignore Easy Questions
Many students spend too much time worrying about difficult questions.
Remember:
Easy questions count just as much as hard questions.
Mastering basic concepts can significantly improve your score.
Tip 20: Use Multiple Practice Resources
The strongest students combine:
- Study guides
- Practice questions
- Practice tests
At Olivia Grace Study Notes, students often pair the HESI A2 Math Study Guide with free practice tests to create a complete study system.
This combination helps reinforce concepts while tracking progress.
Tip 21: Consider a Complete HESI Preparation Plan
Math is only one part of the HESI A2.
You’ll also need to prepare for:
- Anatomy & Physiology
- Vocabulary
- Grammar
- Reading Comprehension
- Biology (if required)
That’s why many students choose a complete HESI A2 Study Bundle rather than preparing for each section separately.
A structured approach often leads to better results and less stress.
Common HESI A2 Math Mistakes to Avoid
Here are some mistakes that frequently cost students points:
- Rushing through word problems
- Forgetting conversion factors
- Skipping practice tests
- Ignoring weak topics
- Focusing only on formulas
- Not reviewing mistakes
Avoiding these errors can significantly improve your performance.
Final Thoughts
The HESI A2 Math section is not about advanced mathematics.
It’s about mastering a handful of core concepts and applying them correctly under exam conditions.
If you focus on:
- Fractions
- Ratios
- Percentages
- Conversions
- Word problems
and combine that knowledge with consistent practice, you’ll put yourself in an excellent position to succeed.
Use practice tests to identify weaknesses, study guides to strengthen concepts, and repetition to build confidence.
The more familiar these question types become, the easier the Math section will feel on exam day.
