Does Engg Graduate means Science graduate?

No, an engineering graduate is not automatically a science graduate. While engineering relies heavily on scientific principles, it's a distinct field of study. Engineering applies scientific knowledge to design, build, and maintain systems, structures, and processes. A science graduate focuses on the discovery and understanding of fundamental principles in their chosen field (physics, chemistry, biology, etc.). They might conduct research, but don't necessarily focus on application in the same way an engineer does. There's overlap, but they're separate disciplines.
