The answer is: it depends.
* If you haven't graduated high school: Most universities require a high school diploma or its equivalent (GED) for undergraduate admission. Some might offer early college programs or dual enrollment options, allowing high school students to take some college courses, but full degree enrollment usually requires high school completion first.
* If you have some college but no degree: You can likely enroll in a degree program. However, your previous college credits might or might not transfer, affecting the total time it takes to complete your degree. You'll need to check with the university's admissions office to determine transfer credit eligibility.
* If you have a degree already: You would enroll in a *postgraduate* or *graduate* program (like a Master's or PhD) rather than an undergraduate degree.
In short, clarify your educational background (high school graduate, some college, etc.) to get a more precise answer about your eligibility for a degree program.
