it's good that you know where u've gone wrong and have tried to
rectify it... Your parents will find out one day, so why not just
tell them directly your grades? If they wanna scold, just let them
scold lor. Anyway you won't lose a piece of meat if they scold you.
Then if they wanna like ground you or whatever, just do as they
say... I'm sure they mean well.
Don't look back on your poor grades ok?
Look
forward in life, learn from your lessons but don't brood over them!
Cheers!
