Disappointed

I am disappointed with my performance in the second Managerial Economics mid-term test... I guess here is the best place for me to release my feeling...

I was able to answer every questions, but when I started to count the marks, marks fly here and there and eventually a big portion of marks will be deducted....

I am very particular with the mistake I made (4 marks confirmed gone).... add up with the deduction from here and there, I guess....Sigh~~!!

The 4 marks make me feel like....I do not know how to express by words, is kind of blaming myself for answering the question wrongly.... Until this moment, my heart still feeling like.....
