After exam released

After exam result was released. I was feeling "meh" no emotions.
Thank God. I just failed this particular subject called Strategic Planning Management.
The rest of the subject I have passed, was wondering why so hard, I have got a grade D. The requirement to pass the subject is C. OH God case studies was hard..... I need to find my tutor and ask the methods of study. This time I have to passed this exam. All the best for those who need to resit some papers for this semester.
