For students

Beta release. Both the application and this documentation are still under development and their content will be revised as the work continues.

This part of the documentation describes how a student signs in to the system, enrols in courses, submits solutions and reads the results of their evaluation.

Signing in and the user account

Sign in using your university account if the option is available on the sign-in page (planned for Q1/2027). Otherwise you have to ask one of your teachers to send you an invitation to the system. Self-service registration is not currently permitted.

The invitation arrives by e-mail and has a limited validity; the date is stated both in the message and on the page the link opens. Once it has expired, ask for a new one — the original cannot be extended. After opening the link, choose a password for the account; submitting the form creates the account.

A forgotten password is reset through the I cannot remember my password link on the sign-in page. This applies only to accounts with a password of their own; for a university account the password is managed by the university.

Confirm your e-mail address using the link delivered to your mailbox once the account is created. The system sends notifications of approaching deadlines, evaluation results and completed reviews to that address. Until the address is confirmed, no e-mail is sent.

Enrolling in a course

Enrolment takes place after signing in, in one of two ways depending on how the course's visibility is set:

1. Open My groups → All groups in the menu and search for the course. If you find it, open its detail and use the Join the group button.
2. Otherwise you have to ask the teacher either to add you to the course directly, or to send you a link that opens enrolment.

Whether you can leave a course yourself depends on that course's own settings: either its detail offers a Leave the group button, or the course information states that students cannot leave on their own. In the second case you have to ask the teacher to remove you. Submitted solutions are preserved even after leaving the group.

Courses and deadlines

After signing in, a student is presented with the Dashboard, which contains:

• Coming up — assignments open for submission, ordered by the nearest deadline. Each row states the course, the deadline, the maximum number of points and the current state of your submissions.
• Calendar — a monthly view of the same deadlines, which can be paged month by month.
• Graded without submission — work the system does not evaluate (an oral examination, a presentation, attendance). Points are awarded manually by the teacher and the stated deadline is informative only.
• My progress — your points so far in each course, including the threshold required to pass where one is set.

The My groups menu section lists the running courses you are enrolled in. The All groups tab may additionally show public groups that you are free to join.

Submitting a solution

Before submitting, read the assignment and its terms carefully — in particular the deadline, the number of points, the maximum number of attempts and the programming languages accepted for the submission.

Having chosen Submit a solution, proceed as follows:

1. Upload the files containing your solution. The maximum number of files and their permitted size are stated above the form.
2. If the assignment accepts more than one programming language, select the one you used. The choice is derived from the names of the uploaded files; where an assignment has a single language, the field is not shown.
3. If your solution consists of several files, name the program's entry point in the File to start field. Without this the solution cannot be submitted, and deliberately so: a default taken in alphabetical order would often start the wrong file, and the result would be zero points that look like a fault in the solution.
4. Optionally add a Note. It is visible only to you and to the teachers of the course.
5. Confirm with the Submit button.

Whether an archive may be submitted depends on the particular assignment. The system matches the uploaded files by name against the pattern given in the exercise configuration — where an exercise expects *.py, an archive does not match that pattern and the submission is refused. If in doubt, submit the individual source files.

Once submitted, the system processes the solution and begins evaluating it automatically. For ordinary programming assignments the evaluation takes a few seconds. There is no need to refresh the page; the result appears by itself as soon as the evaluation finishes.

Assignments without automatic evaluation

An assignment need not contain a program intended for automatic evaluation. A teacher may ask for a text document, measured data, a presentation or a PDF document.

The submission procedure is the same in such a case. The file is not processed automatically, though: the solution is given the state Awaiting grading and no points. Having received the solution, the teacher reviews it and awards the points manually.

The deadline, the maximum number of attempts and any feedback work exactly as they do for automatically evaluated assignments.

The result of the evaluation

Once the evaluation finishes, the system shows the score achieved and the results of the individual tests.

Each test states its result, the score achieved, the time and memory consumed, how close those came to the limits, and the program's exit code.

The attempt as a whole may additionally end in one of these states:

The overall score is computed from which tests passed and from their weights; a teacher may use a formula of their own instead of weighting. A partially correct solution can therefore earn a proportional part of the points.

For tests that did not pass, the expected and actual output can be compared — the Judge output sets out the differences line by line and includes a legend for the notation it uses. How much of the actual output a student is shown is determined by the teacher in the exercise settings.

Where the automatic grade is unsatisfactory, first re-read the assignment carefully and check that your solution addresses it completely. If you are not sure where the fault lies, request a review of the solution, or raise the matter with the teacher at the time set aside for it — during a seminar or in consultation hours. If, on the other hand, you are aware of the fault and have corrected it, you may upload a new solution (up to the configured limit), which will be evaluated again.

As a rule the solution with the highest score is the one that counts, unless the teacher decides otherwise. The exact order of the rules is this: if the teacher has marked a solution as Accepted, that one counts; otherwise the solution with the most points; and where two are equal on points, the more recent one. Submitting a further attempt therefore cannot worsen your grade, though it does consume one attempt.

Deadlines and the number of attempts

An assignment may have a second, late deadline carrying a reduced number of points.

Where the number of submission attempts is limited, the assignment screen states how many you have left. Before submitting, check your solution against the example given in the assignment. How strictly the output is compared is determined by the judge chosen for that particular exercise: some compare the output character by character including whitespace, others disregard the order of words on a line or the order of whole lines.

Requesting a review

The solution screen allows you to ask the teacher for a review. The solution thereby enters their queue and the teacher is notified; the request can be withdrawn at any time.

A review is a set of comments — either on particular lines of the submitted solution, or on the solution as a whole. A comment marked as an issue to fix is a defect whose correction the teacher expects. The comments become visible only once the teacher closes the review.

Examination mode

For the duration of an examination a teacher may lock you into a single course. While the lock is in force the other courses are inaccessible and an invitation link to another group is refused; the lock is released by itself once the examination ends.

Troubleshooting

• The evaluation ended with an infrastructure error. This is not a fault in your solution and it does not consume an attempt. Report it to your teacher; resubmitting is pointless until the cause has been removed.
• You believe the solution is correct, but a test did not pass. Read the Judge output and verify the exact wording of the output, then request a review and state where you believe the test is at fault.
• The solution cannot be submitted. The deadline has passed, you have used up your attempts, the course no longer accepts solutions, or submission is temporarily disabled across the whole instance. The assignment screen states the particular reason.
• No e-mail notifications arrive. Check that your address is confirmed; nothing is sent to an unconfirmed address.
• If you have questions, you may post to the discussion attached to each assignment. For a question about the evaluation of one particular solution of yours, start the discussion in the detail of that submitted attempt.
