Self-study needs structure

The hard part of self-study is structure: which subject today, when to return to last week's subjects, and how to tell what you are retaining. Studying alone, it is easy to fall into rereading whatever outline feels most urgent.

Bengos gives your rule-statement practice that structure. The subjects come in a deliberate sequence, and you work one at a time. Finished rules go on spaced repetition: the ones you are less sure of come back more often, so your study time goes where you need it. The dashboard shows what you have covered, what is due, and how your speed and accuracy are moving.
