Usually, the grading standard of art test will be different according to the differences of different levels and subjects. The grading standards of hard pen calligraphy and soft pen calligraphy will also be different.
Generally speaking, passing Level 3 means that you have passed the exam, but the specific grading standards and qualified scores may vary according to different examination institutions and regions. So I suggest you consult the relevant grading standards and qualified scores to get a more accurate understanding.
In addition, although passing Level 3 means that you have passed the exam, it does not mean that you have reached the level where you can independently engage in calligraphy creation or related work. Learning and practicing calligraphy is a long-term process, which needs continuous improvement and accumulation.
