Can you go to university with 5 o levels only?

No, you generally cannot go to university with only 5 O Levels (or GCSEs, their equivalent in many countries). Universities require a higher level of secondary education, typically A Levels (or their equivalent, such as the IB Diploma or High School Diploma in the US). The specific requirements vary greatly depending on the country, university, and the chosen course of study. While some universities *might* accept 5 O Levels plus significant additional qualifications or experience, it's highly unlikely and certainly not the norm.
