Can social self-taught candidates take the postgraduate entrance examination (take the exam outside without going through school)? So where are the files of the self-study exam? Not a high school file. Social self-taught candidates can take the postgraduate entrance examination, and the Provincial Education Examinations Institute has the office of the Higher Education Self-taught Examination Committee, which is often called the Provincial Self-taught Examination Office. The document is not sealed. Where do you keep your high school files? You can get the self-taught examination files from a trust institution without stamping, but the information inside must be complete (there are three chapters in the general graduation record registration form), and how to give the self-taught examination files to you and the high school file trust institution.
