Premium 1:1 and small-group tutoring that turns math anxiety into deep confidence, strong problem-solving skills, and outstanding results on the SAT, ACT, and beyond.
Rectangle LLC was founded by a team of educators, mathematicians, and former test-prep directors who saw too many bright students lose confidence because traditional classroom instruction moved too fast or too slow.
We built a different kind of math education company — one that starts with a precise diagnostic, crafts a custom learning plan for each child, and delivers instruction that is both rigorously challenging and genuinely joyful.
All programs include our proprietary diagnostic assessment, custom learning plan, and detailed parent progress reports.

Our four-pillar approach ensures every student builds deep understanding, not just short-term test performance.
We begin with a comprehensive diagnostic that reveals exact strengths, misconceptions, and learning style — far beyond a simple placement test.
Every student receives a personalized roadmap with clear milestones, tailored materials, and the perfect balance of challenge and support.
We use research-backed techniques — spaced repetition, interleaving, and rich problem solving — so knowledge sticks for years, not weeks.
Once foundations are rock solid, we introduce advanced strategies, competition-level thinking, and the confidence to tackle anything.
Every tutor is hand-selected, rigorously trained, and has scored in the top 1% on standardized tests. Many hold advanced degrees from top universities and have 5+ years of elite teaching experience.
We track everything. Average 147-point SAT Math gains. 98.4% of parents report significant improvement in both grades and confidence within 8 weeks. Real data. Real accountability.
Parents receive detailed weekly progress updates, video summaries of key sessions, and direct access to instructors. We work as an extension of your family, not just another service.
“Our son went from dreading math and getting C’s to begging to do extra problems. His SAT Math score went from 620 to 780. Rectangle didn’t just improve his grades — they changed how he sees himself.”
“The diagnostic was eye-opening. They identified gaps we never knew existed. Within 10 weeks our daughter’s confidence soared and she scored in the 96th percentile on the SAT. We tell every parent we know about Rectangle.”
“I used to think I was ‘bad at math.’ My tutor showed me I just needed better strategies. I went from the bottom of my class to getting 100s on tests and qualifying for AMC 12. Math is now my favorite subject.”
