How is this program different from a combined BS/MS (also known as a 5th-year Master) program?

The MSSE focuses on providing its students with specialized knowledge and the ability to apply such knowledge in the areas of software engineering, high-performance computing (HPC), molecular science, big data analytics, and entrepreneurship. The Department of Chemistry at UC Berkeley does not currently offer any combined BS/MS degree. The MSSE is the only master’s degree it accepts students into.
