I'm nearing completion of DM certification. I did the eLearning more than a year ago and I would like to re-do the knowledge reviews and maybe even the exams. If I jump in and out of the different sections and re-do some of the knowledge reviews, will I reset my exam scores? I am happy with the scores I have and I don't want to be forced to re-do every section, instead I just want to be able to review certain sections. Is this possible?
