You can look at it according to your own situation. It is recommended not to apply for a job. Most of them are unnecessary. Online classes are enough.

In mathematics, I recommend Tang Jiafeng, Li Yongle, Zhang Yu, Wang Shian and lin li. Zhang Yu's class needs a good foundation to understand. Tang Jiafeng's courses are all basic, and those with poor foundation can choose.

Political recommendation Xiao Xiurong, leg sister to strengthen guidance, Xu Tao to strengthen remedial classes.

Zhu Wei's vocabulary class, new grammar class, new grammar class, new translation class and Gestalt class in Song Dynasty are all good.

For professional courses, it is recommended to focus on finding seniors and sisters in the target colleges or seeing tutors.

The exercise books corresponding to the above teachers can also be bought.

Postgraduate institutions recommend Du Wen Online School, Zhonggong Postgraduate Entrance Examination, Shangyuan Education and New Oriental. They are all relatively old institutions. That institution of Tang Jiafeng can also be used.

Remember to digest the problem when watching the class.

These are all good.
