Persistent Subsection and Course Grades --------------------------------------- Status ====== Accepted (circa June 2017) Context ======= There are several reasons that we need to persist a learner's computed grade in the database, both at the subsection-level, course-level and problem-level. Prior to the introduction of persistent subsection and course grades, only problem-level grades were persisted, with higher-level grades computed dynamically from these problem grades. Decisions ========= More background and the decisions around persistent subsection and course grades are captured in the `Robust Grades Document `_.
