I'm don't understand what's the problem with me. Luck isn't favouring me in the exams. Looking at the paper during reading time, makes me so happy that I can't tell. I usually know the answers of almost every question in the paper but when I'm on my way to home, some of my classmates discuss the answers with me. At that time I realise that I've committed a blunder. Somewhere I didn't attempt a 4 marker by mistake, somewhere I interchanged the answers, etc. Why is this happening?? I've toiled throughout the year yet I'm myself deducting my marks unknowingly. Is this happening with anyone else among my resmates??? |
