Does Shanghai have junior high school science as a subject? As far as I know, there are physics, chemistry, and biology subjects. When I saw the teacher recruitment, is there a science subject?

In the sixth and seventh grades of Shanghai junior high school, comprehensive science is taught, that is, physics, chemistry, and biology are taught, but it is very simple. You will not participate in public examinations, but you will have district academic proficiency tests, school examinations, and district bureau grading after completing your studies. Under the new high school entrance examination, life science (not biology) is not a separate subject examination. For details, please check the Shanghai New High School Entrance Examination online.
