When I was writing my thesis, I searched a lot of information on the Internet, and then sorted it out and printed it out. After listing the outline of my thesis, I classified the information into the corresponding parts in the outline. Of course, if you want to be self-reliant, you can learn from others and write the first draft with your own thoughts and style. If you are lazy, you can organize and edit the collected information yourself!
Remember: self-taught candidates have to rely on themselves, and opportunism is not enough! Always be honest and do things steadily! If you need help, you can email me :hnnyzxh@gmail.com.
