what can you say to those grade conscious students - those student doesn't want to have even low grades? well, i just ask because I am a very grade conscious student. I study hard and sometimes if I had a low grade, I feel very sad and all I can do is to cry. my mother and my brother said everytime that im crying because of my low score, they said that just better luck next time. I passed all of my subjects but I haven't been contented with my grades. my grades is quite high but i didn't satisfied yet. maybe I just want to be as intelligent as my brother did. but its that a problem? kindly give a comment about my problem. thank you.
