The ADR algebra $R_A$ of an Artin algebra $A$ is a right ultra stronglyquasihereditary algebra (RUSQ algebra). In this paper we study the$\Delta$-filtrations of modules over RUSQ algebras and determine the projectivecovers of a certain class of $R_A$-modules. As an application, we give acounterexample to a claim by Auslander-Platzeck-Todorov, concerning projectiveresolutions over the ADR algebra.
