Excuse me, if I graduated from a vocational high school, how can I take the college entrance examination this year?

It's not that complicated. In a word, my education is the same as that of ordinary high school students.

Graduated from technical secondary school, vocational high school or technical school, provided that they have the same academic ability. (Compared with ordinary high school students)

It's that simple.

It's unfair not to take the college entrance examination if you have a high degree.

In short, ask your local education department and you will know everything.
