To achieve this transformation, follow these steps:

1. Identify the subject in the original sentence: "Anyone who comes in late to Mr. Barker's class."
2. Replace the subject with a more concise alternative: "Any latecomer."
3. Modify the verb to match the singular form of the new subject: Replace "have" with "must."
4. Use more straightforward language: Change "good excuse" to "valid excuse" for clarity and conciseness.
