Welcome!
This is a system that allows to formulate and upload documents in a format very close to LaTeX. In addition to traditional LaTeX, there is the possibility to include interactive exercises. The system then presents such exercises to the student in an interactive environment that generates automatic feedback based on the student's answer.
If you are a student, then you should have received links to specific documents that you can read and work on. If you want to be able to restore your progress later, then you should consider creating a user account by clicking on “Register”.
If you are a teacher who wants to make use of the system for his or her own courses, then please contact one of the administrators who can grant the required permissions.
