幫我作篇文....my examination review...超急急急急

My examination has been over ,also , I have already got my paper back . However , it wasn't as good as I expect . Perhaps I have some problems on my revision and hence here is my review .
For the reason of the bad result , I think I haven't had good preparation as I just have my revision 1 week before my examination . Then , I have a lot of subjects and thus I haven't paid my best effort on each of the subject , only have a basic concept for each of them .As a result , each of the subject are not really good .
In spite of the bad result , I never give up ,I think I have to set up a timetable in order to arrange my time well .

我的考試已完結了，我亦取回我的考試卷。但是，成績卻沒有我想像般好．或許我的溫習方式有些問題，因此我作出以下回顧。
對於差勁的成績，我認為我沒有做足準備，因為我是在考試前的一星期才開始溫習，而且，我也有很多科目，亦因為這樣，我沒有負出我最大的努力在每一科上，只有一過初步的印象。結果我的成績當然不好。
儘管我的成績很差勁，但是我並沒有放棄，我要訂立一個時間表去有效地管理我的時間。
