On the pre-med track at the University of Chicago with a 36 ACT, Rhea built her own math fluency from the ground up — and she remembers exactly where the leap from arithmetic to thinking with variables and expressions first felt shaky. She zeroes in on fraction operations and signed number rules as ...

Having taught a test prep course in Hanoi and tutored math across multiple grade levels, Erika knows that the leap from arithmetic to working with variables and expressions is where most students either gain momentum or start losing confidence. Her public policy graduate work required constant data ...

Between coding bioinformatics pipelines and analyzing stem cell data at Stanford, Matthew spent years turning raw numbers into meaningful patterns — a process that starts with the exact skills pre-algebra covers: integer operations, ratios, and translating real situations into expressions. He takes ...

Before medical school, Samantha earned perfect scores on both the SAT and ACT — but what makes her effective in pre-algebra is her Duke training in global health, where she constantly translated messy real-world data into clean mathematical relationships using exactly the ratio, proportion, and vari...

Tiffany's accounting degree means she spent years working with formulas, ratios, and multi-step calculations where one misplaced negative or skipped operation throws everything off — exactly the kind of precision pre-algebra demands when students first tackle signed numbers and order of operations. ...

Medical school runs on the kind of proportional reasoning and equation setup that students first encounter in pre-algebra — and Annie, now a second-year MD student with a physiology background from UCLA, uses those connections daily when calculating dosages, dilutions, and concentrations. She scored...

Pinelopi scored a 1530 on the SAT, which means the integer operations, fraction fluency, and expression-building that define pre-algebra are deeply automatic for her — and she can zero in on exactly where a student's arithmetic starts breaking down as variables enter the picture. Her psychology degr...

Having taught a discrete mathematics class as a TA and run an SAT prep program in high school, Samuel has spent real time figuring out how to make the jump from arithmetic to algebraic thinking feel natural — which is the core challenge of pre-algebra. His applied math studies at Caltech mean concep...

Sami's Duke degrees in Economics and Computer Science both required translating real-world problems into mathematical language — a process that starts with the exact skills pre-algebra covers, like writing expressions, working with variables, and solving basic equations. His 35 ACT confirms that fou...

Engineering coursework — both at the bachelor's and master's level in Chemical and Biomolecular Engineering — meant Earnest spent years relying on the exact proportional reasoning, unit conversions, and expression manipulation that students first encounter in pre-algebra. He teaches these skills by ...
