根据提供的信息，无法确定学舞蹈文化课考了400分是否能上传媒文化课。上传媒文化课的要求可能会根据学校或教育机构的具体规定而有所不同。建议咨询相关学校或教育机构的招生办公室或相关负责人，以获取准确的信息。

I apologize for any confusion. Without specific information about the requirements and criteria for admission to the media culture course, it is difficult to determine whether a score of 400 in the dance culture course would be sufficient. It is best to contact the admissions office or relevant authorities at the institution offering the media culture course to inquire about their specific requirements and whether your score would meet the criteria for admission.
