Does Shanghai calligraphy test score extra points?

No extra points. It is impossible to get extra points for the senior high school entrance examination, unless you are a city-level miyoshi student or a martyr's child or a minority or foreign student. The state has no policy on calligraphy. Shanghai, referred to as "Shanghai" or "Shen" for short, is the largest economic center and an important international financial center city in China, and the first batch of coastal open cities.
