Chris McMillan
Assistant Center Director
I’ve completed College Algebra I and II, Trigonometry, Calculus I, II, and III, Physics, and Discrete Mathematics. This upcoming fall semester, I’ll be taking Probability and Statistics, Linear Algebra, History of Mathematics, and Numerical Methods. I am a highly certified welder with a strong background in both academics and hands-on experience. I hold an ASE certification in suspension systems as a mechanic and have won several school welding competitions, including a state championship my senior year and a 2nd place finish at nationals. Outside the shop, I played football at the collegiate level and earned All-State and First Team All-Conference honors during both my junior and senior years of high school. I also wrestled my freshman year and placed 3rd at the state tournament. Since 2018, I’ve been rebuilding a 1957 Chevy 3100 truck. I’m also passionate about hunting and was a member of a competitive trap and skeet shooting team. On the side, I’ve competed and won in spikeball tournaments as well as having an advanced scoops diving certification. Academically, I scored a 1410 on the SAT with a perfect score in the math section and graduated high school with a 3.8 GPA. For the past two years, I’ve interned at an aerospace engineering company, where I hope to work full-time after graduation. I absolutely love to weld and tinker—whether it’s working on cars or tearing apart any motor I can get my hands on. I’ve fully rebuilt around four engines and have taken each one apart multiple times, always learning something new in the process. Beyond the garage, I’m passionate about sports like football, spikeball, soccer, golf, and many others. And above all, being outside is a necessity for me—it’s where I feel most alive.
Fun Fact: I owned two turtles named TJ and Oogway, my family owns three dogs, and we have two coy fish, 10 goldfish, and one plecko that live in a 1500 gallon outdoor pond.
Favorite Number, Why?: 57 is my favorite number because I see it everywhere—for no apparent reason. It’s a prime number, only divisible by one and itself, which already makes it unique. But what really stands out is how often it appears in my life: on clocks when I check the time, in song durations, and even randomly throughout the day. Coincidentally (or maybe not), my truck was made in 1957, and my favorite era of cars across all manufacturers is also from that same year. There’s just something about 57 that keeps showing up—and I’ve learned to love it.
Education: I go to school at Utah Tech and I will graduate with my bachelors degree in 2028. I went to highschool in Colorado, and my major is Scientific applied mathematics which is very similar to an aerospace engineering degree, only more math focused.
Why I like Mathnasium: When I was in eighth grade, I had a substitute teacher in my band class who knew nothing about conducting or music—but he knew a lot about math. Over the course of two days, he passionately explained the Fibonacci sequence and its surprising beauty. He even showed how the sequence ties into music, but more importantly, he revealed to me that math is more than just numbers, variables, and equations. He helped me see the brilliance in even the simplest patterns and how mathematics is embedded in nature itself. From that moment on, math became easier for me—and more than that, it became fun. I started to enjoy math, to seek it out beyond the classroom. What used to be a subject I disliked turned into something I genuinely loved. That one teacher completely changed how I viewed math. I chose to work at Mathnasium because I want to do the same for someone else. If I can inspire a student to see math the way he helped me see it—to find joy and wonder in it—then I know I’m doing something meaningful. Mathnasium is the perfect place for me to share that passion.
Brady Postma
Assistant Center Director
Fun Fact: In 7th grade, I got second place in the state competitive math test. The guy that got first place was a classmate and friend of mine. We got our names in the local paper.
Favorite Number: Pi
Education: I went to Pineview High School and Dixie State University.
Why I love Mathnasium: Once you get the hang of it, math is beautiful, exciting, even creative and artistic. I want more people to grow up knowing that delight.

FAQ
ACT® tests proficiency in:
Prealgebra
Algebra
Geometry
Trigonometry
Statistics & Probability
In Prealgebra and Algebra, students will encounter operations, equations, and inequalities.
Geometry questions will mostly focus on shapes, angles, and areas.
Trigonometry questions usually include sine, cosine, and tangent functions.
Statistics & Probability questions may involve interpreting data and calculating the mean and probability.
The main differences between the ACT® and SAT® math sections are in the scope of topics and question formats.
Math topics: The SAT® is more focused on algebra and data analysis, while the ACT® includes additional topics like geometry and trigonometry.
Format: The ACT® typically features more straightforward questions, while the SAT® includes complex word problems and multi-step problems that require deeper analysis.
Scoring: The ACT® math section is scored on a 1–36 scale, while the SAT® math section ranges from 200 to 800.
Allotted Time: The ACT® provides approximately 1 minute per question, whereas the SAT® provides around 1.5 minutes per question.
Calculator Policy: Lastly, the ACT® allows calculators for all math questions, whereas the SAT® restricts calculator use to one section.
The range of topics and structure of questions will help students decide how to best prepare for each test based on their strengths and learning style.
A good math score on the ACT® depends on the student's college goals and the schools they're applying to.
The ACT® math section is scored on a scale of 1 to 36, with the national average score being around 20-21.
A score of 24-26 is considered competitive for most colleges and universities. For more selective schools, such as top-tier universities, students may want to aim for a score of 30-34.
The perfect score of 36 is rare but highly impressive.
Students aiming for merit-based scholarships may want to pursue a score of 28 or higher to increase their eligibility.
Ultimately, a good score is one that aligns with the admission requirements of students’ desired schools.
