1, you can register at the local self-study center at any time. If you don't have a junior college degree, you can't apply for an undergraduate course, so you must get a junior college degree first. *** 14 will take 2-5 years at the earliest, and then apply for an undergraduate course for 2-5 years.

2. I don't think there is much hope of restoring my student status upstairs. Now that the school has issued an expulsion document, it has been included in the file, and it is difficult to correct it.

I can give you a good suggestion, that is, choose distance education or online education. Like the self-taught exam, it is a national recognition of academic qualifications and electronic registration in the Ministry of Education. That's easier than taking the self-study exam, but the graduation time can't be advanced. Two years in junior college and two years in undergraduate course.

4. During the four years of studying online education or distance education, you can take part in the work. I think maybe you will go to a blessing in disguise.

I hope my answer can help you!
