What's inside
Original practice
Every published item is written for StudyLoop. The catalogue grows through original school and exam practice without copying official or commercial material.
3-step hint ladders
Stuck? Get a nudge first, then a strategy, then a structured setup — never the answer.
Deterministic grading
Multiple-choice is checked by code today, not by a chatbot. Numeric and symbolic grading should follow the same deterministic rule as they are added.
Local review memory
Choose a nickname profile and your browser remembers practice sessions, missed questions, rubric gaps, and drafts on this device only.
Free forever. No ads. No behavioural tracking. No selling your data.
Every track follows the same rule: original content, visible readiness status, and deterministic grading wherever code can do the job.
