There's no single, universally recognized "blacklist" for colleges. However, Oxbridge College of Business and Management's reputation is highly questionable and it's
generally considered to be a substandard institution, frequently cited as a diploma mill. This means it doesn't meet the academic standards of reputable universities and its qualifications aren't likely to be recognized by employers or other institutions.
While not officially "blacklisted," its low quality effectively excludes it from the legitimate higher education landscape. Many professional bodies and employers will not accept its credentials. Therefore, researching any college thoroughly before enrolling is crucial.
