- I am attending Harvard College.
- My brother graduated from the College of William & Mary.
- She is a professor at Community College.
However, if "college" is used in a more general sense or as a generic term, it is usually not capitalized. For instance:
- I am going to college next year.
- She studied music in college.
- They met in college.
Capitalizing "college" without referring to a specific institution is unnecessary and may be perceived as overly formal or awkward in many contexts.
