The high school proficiency test is only related to the high school diploma. Even if you get all A's, you should take the college entrance examination and be admitted to the university according to the results of the college entrance examination. On the contrary, if there are unqualified subjects in the academic proficiency test, you can also take the college entrance examination and be admitted to the university.
Some schools require academic level scores in addition to the college entrance examination results, but it is impossible to get in without taking the college entrance examination.
