what you sow is what you reap.

SIGHHHH. exams coming up, really can't be stuffed D:
 I'm so lazy...>_>
but if I think about it, the only subjects that I would need to study heaps for, would be GMA and chem :S
everything else isn't that bad |:

"...A man reaps what he sows." Galatians 6:7

As long as you have put in the effort throughout the year, you wouldn't have any need to stress about exams. If you've done the work, your "study" is basically reminding yourself, so that its fresh in your mind. If you've worked hard, then you'll get a good mark, if you haven't been working hard, then you wouldn't deserve a good mark anyway.

people shouldn't complain if they get a bad score, it shows they haven't put enough effort into doing the work.
