BEFORE
YOU BEGIN.

Each course is a downloadable PDF guide or coursebook with the modules listed on its course page. Worksheets, checklists, review prompts and worked notes are included within the PDF. Collections are individual courses, not bundles of every earlier title.

Study is self-paced. There is no fixed completion deadline or promised completion time. The module list describes the scope; your reading, practice and review time will depend on your starting knowledge.

The materials are PDFs. There are no video or audio lessons, live classes or shipped printed books. Images of booklets on this site illustrate the study format.

Free Set and Neon Drop begin with foundation ideas. The other course pages state the intended audience. Intermediate topics assume familiarity with the relevant basics; programming is not required for the written scenarios.

You can keep the downloaded files on your own device for personal study under the licence in our Terms of Service. No fixed study deadline is imposed. Keep a backup: download links and online storage are not promised to remain available indefinitely.

There is no fixed update schedule. Published changes are recorded on the Last updates page. A purchase does not include a promise of future editions or continuing updates.
