It's time to work me hard!

Finally daddy promised me that he will buy me iPhone.
But the requirement is, I've to score 3As in my mid-year exam.
It's a good requirement, I think so.
Why was I said so ?
Only fulfill me with the stuff that can forced me to work hard on my study.
Which means I can get the stuff what I wanted, work hard on study, take care on study, pay attention when I'm tuition, and get the good result.
So that can study in a good college.
See, how many benefits I got of this requirement ?
So, I've to work hard started from now.
I've just finished only 1 topic of the Science Form 4, still has 7 topics to go.
I wished to continue to do the revision, but I'm really couldn't understand at all.
So I prefer to ask my teacher on tomorrow.
I wished to finish the Science Form 4 in this week.

*God bless!
