In the case of online participation, the Computer Olympiad office will send the required number of logins for the number of learners entered. The Olympiad computers do the marking (no marking for the teacher) and the results are sent to schools.
Pen-and–paper results are marked by the teacher (easy – just tick, tick, tick) and the results are sent to the Computer Olympiad office to add to the national results.
