How we're different

Our mission is to create access to education and provide more opportunities for students to achieve their higher education goals worldwide. We believe that online learning can and should be more than reading pages of text and watching videos of a person who you’ve never met and probably never will. Real people, real teachers and genuine contact can make a good experience great. And we should know, as part of Oxford International, we’ve been helping international students achieve exceptional results for 30 years.

Students and professionals use OI Digital Institute

The level of teaching, experience and patience from the course providers was absolutely incredible. It was intense, there was a lot to learn in a short space of time, but it was structured to ensure it was taught and consumed at an attainable pace. It was extremely rewarding.
