Assessments can be stressful and you surely want to know if you have submitted your assessment correctly. Sometimes the assessment progress in Claned can say 50% instead of a 100%. Assessment progress of 50% can be because of two things:
Ungraded questions means that your teacher has to manually grade your written responses in order for you to get a grade. Therefore, the 50% means that you teacher has still not done this and Claned considers your assessment as incomplete until you teacher has given their points.
There is no need to worry about this and your teacher will let you know your score.
A failed attempt
If you know that there were no questions that need manual grading (written questions or submitting files always require manual grading from the teacher) or your teacher has given their points, this means that unfortunately you did not get enough points to pass the assessment.
