This is the exact calculator system that helped thousands of neurodivergent students turn time management from their biggest weakness into their secret weapon—without “just try harder” advice that never worked anyway.

Intersection clicks, vertex shortcuts, regression in seconds—clear, repeatable steps that reduce decision fatigue. No more “figure it out as you go.”
“If it’s one click, Desmos. If it’s 2-3 clean steps, by hand.” Eliminate the mental ping-pong of deciding what to do.
5 real SAT questions with step-by-step Desmos walkthroughs. See exactly how it works before test day.
Polynomial behavior checks, symmetry tests, ratio validation—the uncommon hacks that turn good scores into great ones.
The mistakes students make most (especially under time pressure)—and the quick fixes that actually stick.
A practice schedule that builds automaticity, not just understanding. Because knowing isn’t the same as doing it under pressure.
For students with ADHD, dyslexia, anxiety, test accommodations, or anyone who’s been told they’re “smart but just need to focus”:
"I'm incredibly proud of my new score, and I'm amazed how simple it was. Tatum customized each lesson to be a thorough review and explanation of my previous mistakes; and as a result, I practiced my weaknesses more than traditional preparation courses. She frequently asked questions to aid my understanding, and she answered all of my questions helpfully."
"Tatum is so dedicated to helping each and every one of her students succeed. She doesn’t just help you with the SATs she gives you advice that you can use in your classes and in everyday life. I am forever grateful for her help I could not have done it without her. I could not have asked for a better tutor!"
"Through focus on personal goals, positive reinforcement, intuitive instruction, light-hearted interactions, and customized assignments, my daughter’s writing and math (and her attitude and motivation) have improved ten-fold. She brings a wonderful mix of knowledge about the subject matter, experience with making it relevant, responsiveness, empathy, and assertiveness. Her personality and approach have resulted in my daughter regarding Tatum as more of a mentor than tutor... and that has made all the difference!"
