Writing tips for CMIT 320

Follow the assignment instructions and rubric line by line

UMGC assignments for CMIT 320 are graded against a specific rubric or grading criteria your instructor provides — every requirement has to be visibly addressed. Skipping a requirement because it seems minor is one of the most common reasons a strong submission loses points.

Document lab work step by step, not just the final result

CMIT courses like CMIT 320 are heavily lab-based and often certification-aligned — evaluators want to see the actual configuration steps, commands, or tool output that got you to the result, not just a final screenshot or conclusion.

Ground your work in the specific technology or platform named in the assignment

Many CMIT courses are tied to a specific vendor platform (Cisco, AWS, Azure, Red Hat) with its own terminology and tools. Using generic networking or security language instead of the platform-specific terms the assignment expects is one of the fastest ways to lose points.
