"The titration simulation helped me understand equivalence points in a way lectures never could. Worth every penny."
"We rolled this out to 200 first-year students. The engagement increase in our physical chemistry module was remarkable."
"I use the reaction kinetics sim to teach Arrhenius theory. Students finally get why catalysts lower activation energy."
