Prepare the content of your re-examination exam. Although the online exam is shorter than the offline exam, it can not be underestimated for the preparation of professional courses. For official website's designated bibliography, find out the key points and suit the remedy to the case by combining the real questions. Some students may say, what if you haven't studied undergraduate? So I actually have a say in this. I took three re-exams, only one undergraduate course, but I forgot a lot. For the courses you have studied, brush the key points in the book and the exercises after class.

For courses you haven't studied, find videos on the Internet to brush your notes. Functional analysis study, recommend the course video of Inner Mongolia University. For the online exam form, it will let everyone prepare blank paper and display it on the screen after answering the questions.
