Graduation thesis has little to do with postgraduate entrance examination. Even if your graduation thesis is not well written, it won't affect your postgraduate entrance examination, because the tutor basically won't read your graduation thesis, but if you write well, you can mention it a little during the interview, which can also prove your ability and leave a deeper impression on the tutor. But these are not the key points, the most important thing is your initial test results and re-test results, so prepare for the exam.
