If you apply for the calligraphy department, after the college entrance examination, you can choose the school where your calligraphy scores are admitted according to your scores. Some good schools, such as the Central Academy of Fine Arts, have scores in English and Chinese, but Qu Normal University doesn't, as long as the scores are over.
Calligraphy majors in all universities in China belong to one book. If you just want to add points to the college entrance examination by calligraphy, it seems that there are no special students to add points now.
The national college entrance examination is unified. On July 7893 or July 782, key universities in the province will participate in the unified marking after the college entrance examination. Therefore, it is not the school that has the final say, but the provincial education department has the final say. Nowadays, the social repercussions caused by the extra points in the college entrance examination are great, and many projects have been cancelled.
The first prize in the single subject of Mathematical Physics and Chemistry Competition will be awarded 10, with a maximum of 20 points per person. Calligraphy expertise will definitely not be higher than 10. For details, you can ask the high school teacher or check the dynamics of your provincial education department. However, good words play a great role in Chinese composition. I have experienced it personally, unlike the gap of 5 to 10 as the teacher said.
