The future education examination system includes computer version software and mobile phone version question bank. Here, taking "Secondary MS Office Basic Question Bank" as an example, the usage of this system is introduced. Precautions for the use of activation code: Both the computer version of the software and the mobile phone version of the question bank need to use WeChat to log in, and then use the activation code to activate. The activation code will be bound to this WeChat account and cannot be used for other WeChat accounts. The same activation code can activate the computer version of the software and the mobile phone version of the question bank at the same time. If you activate the computer version of the software first, the mobile version of the question bank can be directly logged in, and there is no need to activate it with an activation code. If the mobile version of the question bank is activated first, you need to activate it with the activation code when using the computer version of the software. An activation code can only activate two computers (that is, an activation code can only be used on two computers at most), and the validity period of the activation code is 2 years (from the time when the activation code is used).
