The term "college years" refers to the period of time when an individual is attending college or university. This typically spans from the age of 18-24, although it can vary depending on factors such as taking a gap year, transferring schools, or pursuing higher education later in life. The college years are often considered a formative period where individuals develop independence, self-discovery, and establish their career goals. It is also a time of significant personal growth and development, both academically and socially.
