“Sorry for the late e-mail it slipped my mind to ask, I was wondering when would be a good time for me to make up my Exam?”
Sometimes it is difficult to come up with a simple, clear, concise response that is not mean or ill-spirited but yet still conveys the appropriate information while dispelling the obvious assumptions and activities that the question indicates.
The exam was more than 10 days ago. The syllabus indicates that there are no make-up exams except in rare, unusual circumstances that have not been indicated nor discussed. Making up the exam is irrelevant because passing the course is no longer possible because you have missed 4 of the 8 labs we have done so far.
