Not sure where this goes:
In Nuclear Navy training, if a student did poorly on an exam or practical, an "REMEDIAL" was issued. This was in addition to the standard qual card, requiring a student to make up, re learn, recheck out or requalify on the items missed. It required extra effort to maintain timing of the program requirements. This also happened with qualified operators at times.
in civilian education, Some professors have given make up exams or second (even third) exams so that students could get good grades... and demonstrate knowledge or proficiency... wanting to be on the students side instead of the judge side.
