Is there an examination system that can randomly select questions?

1. Of course there is. The online examination system can build a question bank by itself, and then randomly select questions and groups. Random group paper strategy is one of the features of the online examination system. In order to prevent cheating, traditional paper examinations often have two forms of A and B volumes, which are relatively complicated in workload.

2. Use the online examination system to randomly select group papers, which can quickly complete the group papers. The content of each examinee's test paper is different during the examination. This way of grouping papers can more comprehensively test the mastery of candidates' knowledge and prevent candidates from plagiarizing each other during the examination process.

3. Random test paper: It is selected from the classification and question types of test questions in the test bank. The division requirements for the classification of test questions are relatively high. You can add multiple questions and random selection strategies. You can also set the number of questions and test scores according to your needs, and you can form multiple sets of test papers.

4. You can use the WeChat applet [Answer Star] to answer the exam. Open this answer applet system on WeChat to use it. There is no need to download and install, and it is free to use.It can be used for the answering activities organized by the unit itself, and can be answered online.

5. The sampling test papers and random test papers are both random groups, but the random test papers have relatively high requirements for the classification of test questions, so the test questions should generally be imported into the test bank before creating the test, which is convenient to quickly add test questions when grouping papers.

online examination system, which one is more convenient? Do you have any recommendations that are easier to use?

Examination Treasure is a permanent free e-homework and online examination system cloud platform.

The online examination system is a relatively popular tool for organizing examinations in recent years.

Graduation design is suitable for jsp or mvc

1. The back-end graduation design can use the front-end template, the front-end can use the BootStrap framework, and the back-end code can use JSP to implement it.The front-end is the front-end part of the website, which runs on the PC terminal, mobile terminal and other browsers to display the web page to the user.

2. In MVC mode, because the system is opened layer by layer, the division of labor in development can be better realized. Web designers can develop JSP in the view layer. Developers who are familiar with the business can develop the business layer, while other developers can develop the control layer. It is conducive to the reuse of components. After stratification, it is more conducive to the reuse of components.

3. Easy to do, it mainly depends on what content you do and the size of the system. For JSP resources, general JSP resources need to be charged. There is basically no free one. Or it's basically garbage. It's useless to take it.

4. It is recommended to use jsp+servlet. It is relatively simple. There is no need to read java programming ideas for graduation design. That book is too in-depth.Learn html and learn jsp, servlet can do it, which is enough for the graduation design of ordinary schools. Or it is relatively simple to choose asp.net.

5. In the MVC design mode, there is a short whip with a circle at one end: c represents the controller, which is responsible for the communication control of the user interface and the business logic layer. On the one hand, it interprets the input from the user interface, identifies user actions (such as clicking buttons, etc.), and calls the methods in the corresponding model.

The significance of the topic selection of the gasoline fuel supply system

1. The function of the fuel supply system is to provide a certain pressure of fuel to the injector so that the fuel injector can inject fuel according to computer instructions. The oil supply system of gasoline engines plays a very important role.

2. The purpose and significance of this situation are as follows: Meaning: Accurately control the fuel supplied by the fuel supply system, fully improve the concentration ratio of combustible mixed gas, make the fuel fully burned, and improve the fuel economy of the automobile. At the same time, an advanced ternary conversion device is adopted in the emission system, which can minimize the emission of automobile exhaust gas.

3. Its function is to convert the chemical energy of a liquid or gas into thermal energy through combustion, and then convert the thermal energy into mechanical energy through expansion and output power to the outside world. The power of a car comes from the engine. The engine is the heart of the car, providing power for the car to walk. The car is dynamic, economical and environmentally friendly.

4. The function of the fuel supply system of the automobile engine is to pump the fuel out of the fuel tank and filter it.After pressing, it is provided to the fuel injector, and then the control unit controls the fuel injector to inject into the intake pipe of the engine to participate in the engine combustion.

5. When a = 05~15 thin mixture is used, it can be ensured that all gasoline in the mixture can obtain enough air to achieve complete combustion, so the engine economy is the best, so it is called economic mixture.

6. According to the different requirements of various working conditions of the engine, a certain amount and concentration of combustible mixed gas is mixed and supplied into the cylinder, so that it ignites, burns and expands at the end of compression, and finally discharges the exhaust gas after combustion into the atmosphere.
