Website for Remote Learning

This is a website for remote controls. It realizes a lot of different things: entry/registration as a teacher/student; creation of control, and editor tasks; viewing the assessments of all students (for the teacher); viewing all their assessments (for the student); sending the specified control to the students; resolving the control (the student); the ability to comment on each task of the student by the teacher and put the balls; and many other little things. In the control editor you can create: a test task (maybe with a few answers) or a text task (maybe with a picture). The site is made in HTML, CSS, Javascript (pure without frameworks), PHP. And also launched on the server for access from the internet.
