STEPWISE is a Grade 12 math + physics learning studio built around saved work. In each Studio Session you draft a step-by-step reasoning trace, verify each step with hints, write a short reflection, and remember it as a Notebook entry. Session types include StepSolve, Misconception Check, Units & Assumptions, and Error Fix. Search and pin entries, complete daily studio prompts, and run Review Sessions that summarize weak steps and recurring error patterns. Everything is stored locally on your device.
