You can choose the way of self-examination,

Not necessarily graduated from junior high school,

If you don't need it in primary school, you can take the college entrance examination.

There is no entrance examination for the self-taught examination, and you can register regardless of age, gender, school status, place of origin or racial restrictions.

Self-taught undergraduate students need a college diploma.

So you can choose to study in a junior college, or you can take a remote junior college exam and take an undergraduate exam by yourself.

I hope the answer can help you, or you can ask.
