OU you kind of miss the experience and also the relationships you can build with your classmates which sometimes can help you later in life. Its also easier to get distracted and feel disconnected when just you have to do the work with only online contact. It also isnt as highly regarded as a Russell group, if you want to go into more prestige jobs like banking, law, engineering, and work for big global names thats not the best springboard. Its not impossible but there are simply better names you can put on a degree the OU.
