First, take the college entrance examination in higher vocational colleges and enter full-time colleges. In the third year of junior college, I took the special entrance examination and entered the undergraduate university. If you need to take the 3+ certificate, you'd better report to the remedial class. After all, I haven't studied hard in vocational school for several years, and I'm about to forget it. I signed up for the vocational college entrance examination remedial class of Guangzhou Yide Education. The teacher was patient and gave a good explanation.
