uchus.online
An educational portal for students who want to pass the exams. I wrote it alone and completely from 0. There are both free elements and paid ones that can be bought directly on the site for money. All paid content has a small trial period, which is configured through the admin panel.
Basic:
- tasks are questions with a certain type of answer that can be customized in the profile.
- Tests - a set of tasks that you cannot answer separately. checking tasks only 1 when you have completed the entire test.
- Forum: a regular forum, but it has hidden parts. only a part of the posts is available to users without rights. another part is available to those who have purchased paid content.
Advanced:
- Courses are free or paid tutorials that can be used to learn a particular topic. the course is divided into chapters. chapters can contain lessons (text with the ability to add a video and a test), tasks and quizzes. there is only 1 quiz per chapter and is generated based on the given test data + the student's personal progress. it then works as a test until it is sent for verification
- homework is an additional paid service in the courses that is purchased separately and gives you the opportunity to work with a mentor. you solve a number of problems on a sheet of paper, take a photo of your solution and send it to the mentor in a hidden thread on the forum, which is available only to you and your current mentor. then you discuss it with the mentor and when the correct answer is received, the mentor marks the homework as completed.
- PVP arena is a free feature where you can invite a friend to a battle and find out which of you knows a particular topic better. one of you sets up the battle, generates a link and sends it to the other. the latter goes to the link and confirms his readiness. then the battle begins and you need to score more points than the opponent.
I have described only the basic things. The product itself is even more complicated.
