Is there a possibility to reattempt the quiz so that the latest grade is the one assigned? I am not sure about the policy here. Apologies if this has been clearly explained in the first lecture and has to be repeated here.
You only have one attempt at the quiz. It is not explicitly mentioned but I think it is a reasonable assumption. The syllabus has been updated (b3562b5fa7e2a297a19ab69339ff1cbea3a0a954) with this information.
