This positioning is stronger than simply calling it “Physics Notes” because “Physics of Materials + AAS101B/AAS201B + AKTU + Mechanical Engineering” directly targets the students who are actually searching for this specific stream-specific course. The PDF itself explicitly identifies it as a stream-specific ME course and distinguishes it from a generic first-year physics course.
