有关专家对于选择免费网站、网校学习的学生提醒:网络学习有些并不是完全免费,学生在学习时需要注意以下几点: 只在线答疑免费有的网站只将在线答疑免费,课程部分收费。答疑平台没有主题,没有固定科目,只有一个老师在线。很多时候一个老师需要面对上千甚至是上万的学生。学生提出的问题有时得不到回复,很多学生没有机会发言。尽量避免到这群的网站,以免浪费宝贵的上网学习时间。 Experts remind students who choose free websites and online schools to learn that some of the online learning are not completely free of charge. Students should pay attention to the following points when they are learning: Online-only Q&A Free Some websites will only provide online Q&A for free, and some courses will be charged. The Q&A platform has no subject, no fixed subjects, and only one teacher is online. Many times a teacher needs to face thousands or even tens of thousands of students. Problems raised by students are sometimes not answered, and many students do not have the opportunity to speak. Avoid this group of websites as much as possible so as not to waste valuable online learning time.
