# Restudium > A learning system for the ever-curious software engineer. Curated teaching, > practical checks, progress and spaced review help build engineering understanding. Restudium is in private beta, starting with one reviewed software engineering book course. Sources are selected, teaching is prepared with AI assistance, and lessons are reviewed against their sources before publication. A sitting includes one new idea or a chapter test, plus up to three due reviews. Learners assess their own answers; points recognize study achievements and recall milestones. The public beta list records interest. Joining does not create an account or grant app access. There are no self-service uploads, public course catalog, paid plans or announced date for open access. Concept courses drawing on several sources and connected learning paths are future direction. Learning outcomes are still being evaluated. The study app and source course material are private.
