考生身份怎么填

I am not sure what specific context you are referring to. However, if you are asking for how to fill in the identity section as an exam candidate, it would depend on the type of exam and the instructions provided by the exam organizer. In general, you would need to provide your name, contact information, and some form of identification such as an identification number or a government-issued ID. It's important to follow the instructions carefully and provide accurate information to avoid any issues during the exam.
