Here's a breakdown:
* Capitalize proper nouns: These are specific names of people, places, or things. So you'd capitalize "English" (the language) but not "English class".
* Don't capitalize common nouns: These are general terms, and subjects like "social studies" fall under this category.
Example:
* I'm taking English and social studies this semester.
* My favorite subject is math.
Exceptions:
* When a subject is part of a title: You would capitalize it, like "AP English Literature and Composition".
* When the subject is part of a proper noun: For instance, "The History Department" or "The Physics Club".
Remember: Always double-check your style guide or the specific requirements for your work if you're unsure.
