Pre-med coursework at Duke put Caitlin through the full general chemistry sequence, so she's recently wrestled with the same topics — stoichiometry, gas laws, equilibrium — that high school students encounter for the first time. She teaches the mole concept by anchoring it in proportional reasoning,...

St. John's College requires students to work through laboratory science using primary sources rather than standard textbooks, which means Kelsey learned chemistry by retracing the reasoning of Lavoisier and Dalton. She brings that same emphasis on understanding *why* reactions balance or why periodi...

Peer tutoring chemistry through her university's program while pursuing a medicinal and pharmaceutical chemistry degree, Madeline spends her weeks toggling between the high school fundamentals and the advanced applications they lead to — which gives her a clear sense of exactly where concepts like e...

I am a law student, but I took an unusual route to get there. I used to attend medical school but had a change of heart in my career path. Part of this was due to my political science major (double major with biology) in college as well as a number of Spanish and other courses that I took. Tutoring ...

Most high school chemistry struggles come down to one thing: the course asks students to think at the atomic level about things they can't see. Qiwei bridges that gap by using visual models and step-by-step problem breakdowns for topics like electron configurations, chemical bonding, and stoichiomet...

Balancing equations and stoichiometry problems often trip students up because they skip the underlying logic of what atoms are actually doing in a reaction — Viral's biology coursework means he's had to apply those chemical principles in contexts like cellular metabolism and enzyme kinetics, not jus...

The math in high school chemistry trips up more students than the chemistry itself — balancing equations, converting moles, interpreting rate graphs. Payal's physics training means she's deeply comfortable with dimensional analysis and algebraic problem-solving, so she can zero in on exactly where a...

Jessica's biology degree with a chemistry minor means she spent years in labs where stoichiometry and solution prep weren't abstract homework problems — they were Tuesday afternoon. She teaches high school chemistry by anchoring concepts like molar conversions and chemical equations in the hands-on ...

Balancing equations, mole conversions, and electron configurations are where most high school chemistry students either gain confidence or lose it. Michelle breaks these topics down by connecting them to the biology and biochemistry she studied in depth — showing, for example, how oxidation-reductio...

Stoichiometry trips up most high school chemistry students not because the math is hard, but because the conceptual steps between a balanced equation and a mole calculation aren't obvious. Susie walks through each step explicitly — molar mass, limiting reagents, percent yield — and ties reactions ba...
