Sort:  

it's really frustrating, and I still can't stop thinking about it.

SOrry to hear! I hope you can sort that out

yeah, hopefully I can do my best next time...

Sorry to hear that. Have to tried explaining to your teacher about it?

apparently that teacher takes no explanation... so the best way to cope with it is just to accept that grade and do my best next time... hopefully.

I see. I remember I had a teacher who gave me a hard time at the beginning of my course. At the end of the sem, he became of my fave teacher because I realized that he’s just teaching me about discipline. Thankful about it

samee... I had once an instructor who gave our whole class a hard time—I mean he really never missed a day pointing our mistakes in the most insulting way...

Of 'course we seek to prove him wrong, so we gave our best not to live his grim expectation for us—and yeah, it ended well because it turned out he's just fueling us to do our best because he saw potentials in us... hopefully this teacher will also that same effect on me..
