"1+1 College" could refer to various educational institutions or programs that use that name or a similar one. However, without more specific context, it's difficult to determine exactly what you are looking for. It could be an institution, a specific academic program, or a unique approach to education.
If you're referencing a specific college or educational model, providing more details would help in giving a more accurate answer. Alternatively, if you're asking about the concept of combining fields of study (1+1 meaning integrating two subjects), please clarify that as well!
