Relatively speaking, if you take the self-taught exam, the difficulty of Chinese language and literature major should be slightly lower. I suggest you consult the Self-taught Examination Office of Shandong Normal University to find out the subjects, the purchase of teaching materials and the scope of the examination, and then start preparing for the self-taught examination. If I have enough study time and strong consciousness, I don't have to apply for remedial classes. If I don't have enough study time and my consciousness is not strong, I suggest signing up for a remedial class, but the quality of the remedial class is uneven. I suggest you make a multi-party investigation before deciding which remedial class to enroll in.
