I am a student in the Business Administration Program. This semester, I am taking a software application course from Mr. Blinnoff. This course is a critical one to implement all knowledge I am gathering from the others courses. Therefore, I would like to attend all classes of this course. Unfortunately, I will have to go back to my country for one week. I am writing to request taking a week off during this course.
I received terrible news from my aunt yesterday. My mom is in terrible health conditions and has been staying in the hospital for the last couple of days. I will have to return to my city to visit my mom and spend time with her for at least one week. Meantime, I do not want to miss any classes of the main course.
For these reasons, I will be grateful if it is possible to provide a chance me to cover the missed classes by taking evening classes after returning to the city.
I would like to hear from you.
Sincerely
