Hi Yanni,
In this case, it would be best to contact the helpdesk with a request to delete one test result due to unexpected disturbances you experienced when you took the test.
Under My Statistics, check the Details tab, which lists all your exams and quizzes. Provide the ID (last column) of the exam that you want to be deleted.
Best of luck in your exam preparations,
