Delayed retrieval and prerequisite connections

Return to this delayed-retrieval set after studying other material, rather than immediately after the module checkpoint. Ten interleaved problems reconnect systems, matrices and partial fractions with polynomial functions, domains, geometric transformations and logical verification. The single-select and multiselect format uses independent tasks without topic labels, and explanations are intended for review after an unaided attempt. This extension review samples retained reasoning and transfer; it is not a validated diagnostic or proof of independent written mastery. Use errors to choose targeted revision before trying further cumulative work.
