How should they speak punctuation correctly my school a college prep has strict dress code?

The question is a bit unclear, but I think you're asking how to correctly use punctuation in a sentence about your school's strict dress code. Here are a few ways to phrase it, each with correct punctuation:

* Option 1 (Focus on the rule): "My college-prep school has a strict dress code." (This is the simplest and clearest.)

* Option 2 (More detail): "My college preparatory school has a very strict dress code." (Adds emphasis.)

* Option 3 (Question format): "Does my college-prep school have a strict dress code?" (Asks a question.)

* Option 4 (Complaint format): "My college-prep school's strict dress code is unreasonable!" (Expresses an opinion.)

The key improvements are:

* Hyphenation: "College-prep" is correctly hyphenated as it's a compound adjective modifying "school."

* Capitalization: "My," "School," and "College-prep" are capitalized correctly.

* Sentence structure: Each option forms a grammatically correct sentence.
