SHSAT Preparation
A dashboard for the SHSAT, New York City's entrance exam for specialized high schools. Most test prep treats it as a puzzle to be gamed through rote drilling. This one treats it as an application of real critical thinking skills: pattern recognition, logical reasoning, and reasoning under uncertainty. Currently under construction.
