If you can't finish your graduation thesis, you should carefully analyze what the problem is from the second year of research:
1. Is your basic professional level too weak? You can go to the library to strengthen self-study, and the postgraduate entrance examination time is very free.
2. Is the experiment involved in the graduation thesis difficult to carry out? You can find a tutor to explain the situation and create conditions with the help of other disciples.
3. Is the writing level too poor to express the meaning? You can download some other people's papers first, carefully read and study the framework and writing ideas of graduation thesis, write from the first chapter, and learn to write here.
First, you have to believe in yourself. If you can get into graduate school, you can pass the procedure. You can do it!
