I can't. In the online class of National Open University, computers and mobile phones can't watch online classes at the same time, which is directly related to the operation mode of online class platform. At present, online class has become a normal state, and related software has developed an online live class module. Under this module, the mobile phone and the computer can log in to the account at the same time, but because the online course needs real-name authentication, the computer and the mobile phone can't surf the Internet at the same time.
