PHD / DBA / Doctorate without oral defense

Non from credible schools. There are plenty schools that would give you a doctorate in one or two years with no defense but with no accreditation or prestige.

Universidad empresarial in Costa Rica does not require defense but we are talking about a school with almost no credibility.

 

Any other tips?

 

1) Either you're going to do a doctoral degree with a dissertation and a defense of that dissertation or
2) you're not going to do a doctoral degree
