Mathnasium of South Barrington's personalized math test prep programs are designed to help students at every level feel confident and prepared on exam day.
Following personalized learning plans, our tutors help K-12 students master the concepts behind every upcoming quiz, unit test, and final exam. From elementary math through Precalculus and beyond, we target the exact skills each student needs so that classroom exams become an opportunity to demonstrate what they truly know.
We align instruction with state standards to prepare students for the math portions of the Illinois Assessment of Readiness (IAR). By identifying each student's knowledge gaps and building understanding level by level, we help students approach their state assessment with the skills and confidence needed to meet and exceed grade-level expectations.
Our specially trained tutors prepare high school students for the math sections of the SAT®, PSAT®, and ACT® using proprietary test prep materials and personalized learning plans. We focus on building lasting content knowledge and exam-ready problem-solving strategies, so students see real score improvement on test day and beyond.
At Mathnasium of South Barrington, our specially trained math tutors help K-12 students prepare for any math exam, from classroom quizzes and state assessments to college admissions tests like the SAT®, PSAT®, and ACT®.
We work with students in a caring and fun group environment, providing personalized, face-to-face instruction that focuses on genuine understanding. Our tutors pinpoint each student's knowledge gaps, introduce concepts in a logical sequence, and guide them steadily forward, so they feel prepared and capable when exam day arrives.
We use the Mathnasium Method™, our proprietary teaching approach that combines assessment-based personalized learning plans with proven interactive techniques to build the mathematical understanding students need to perform well on any exam.
Rather than drilling test-taking tactics, our tutors help students truly grasp the concepts they'll be tested on. Paired with proprietary test prep materials, this approach develops the problem-solving skills and confidence that lead to meaningful, lasting improvement.
Students begin their Mathnasium journey with a diagnostic assessment that helps us pinpoint their current skill level, knowledge gaps, and exam goals. Using these insights, we design a personalized learning plan that targets exactly what each student needs to work on.
Tutors follow each plan closely, reinforcing understanding and introducing new material gradually. As students build skills and fill knowledge gaps, their confidence grows alongside their readiness, so they arrive at their exam prepared to do their best.

At Mathnasium of South Barrington, we believe the best exam preparation is building deep math understanding and mastery over time.
Students begin their enrollment process with a diagnostic assessment that helps us identify their current skills and knowledge gaps. From there, we create a personalized learning plan that builds math skills consistently, session by session, so students aren't starting from scratch before every test.
Our specially trained tutors work with students across any K-12 math class, from elementary math through Precalculus and beyond, reinforcing the concepts they're learning in school, filling in foundational gaps, and developing the problem-solving skills that serve them on quizzes, midterms, and final exams alike.
When a major exam is approaching, we can align instruction with the specific topics and concepts it will cover, so students walk in feeling prepared.
Yes! Our South Barrington tutors prepare students for the math portions of the IAR.
Our tutors align instruction with the Illinois Learning Standards for Mathematics to ensure students have a solid grasp of the grade-level concepts they'll encounter on the exam. We identify each student's knowledge gaps through a diagnostic assessment and build a personalized learning plan that targets the skills they need to meet and exceed grade-level expectations.
The sooner the better. Since the IAR evaluates the math skills students have developed over the course of the school year, consistent preparation throughout the year is more beneficial than last-minute preparation.
We encourage families to reach out at the start of the school year, so we have enough time to address any knowledge gaps and build foundational skills.
If your student's exam is approaching sooner, contact us and we'll develop a focused plan based on the time available.
Yes! Mathnasium of South Barrington prepares high school students for the math sections of the SAT®, PSAT®, and ACT®.
Our specially trained tutors use personalized learning plans to build the content knowledge and problem-solving strategies students need to perform their best on test day. Whether your student is taking the exam for the first time or looking to improve their score, we tailor preparation to their current skill level and target goals.
We recommend starting at least three to six months before the exam date.
College admissions math tests cover a wide range of topics, from algebra and data analysis to geometry and, on the ACT®, trigonometry. Students who begin preparation early have time to identify and close knowledge gaps, build fluency with exam-style problems, and develop the confidence that comes from sustained practice.
For students with significant gaps in foundational math skills, starting even earlier, in middle school or early high school, gives them the strongest possible foundation heading into test prep.
If your student's test date is approaching sooner, contact us, and we'll build a focused plan around the time they have.
Mathnasium of South Barrington offers math test prep as part of a flat monthly membership fee. Pricing depends on your student's individual plan and session schedule.
For specific pricing information, please contact our center directly, we're happy to walk you through the options and find a plan that fits your student's goals and your family's needs.
The number of sessions depends on your student's current skill level, the exam they're preparing for, and how much time is available before test day.
As a general guide, most students preparing for a major exam such as the SAT®, PSAT®, or ACT® attend two sessions per week over three to six months. For state assessments or classroom exams, the timeline may be shorter depending on the student's starting point and goals.
After the diagnostic assessment, we'll have a clear picture of what your student needs and can recommend a session schedule that gives them the best chance of success.
