I'm attending a Dual Course of Study University, where a regular semester is compressed to 3 months and the other 3 months are occupied by working 40hr/month with a selected partner.
From time to time it happens that the students have to attend an exam during their working term. This is true in my case. Therefore, I already sent a formal request to get a day off for the exam (4hr + 1 hr commute each way), as this is specified in our examination regulations.
Unfortunately, the responsible manager has not yet replied. After 5 days I sent in a reminder, to which I also didn't receive a response.
Should I send a 3rd request (2nd reminder) or should I wait longer?
