请英语好的朋友帮助纠正一下翻译错误：“Dear Professor: 我没有收到你。。。”

因为要查分的事情，我发过很多次邮件了，但是Professor就是不会信。我希望他能够去复查一下我期末的考卷。（同时我又怕因为发了太多次邮件而惹怒他，所以希望这份信的口气一定要客气真诚。）

（中文是想要表达的意思，翻译不必和中文完全一样）

中文部分：
Dear Professor:

我没有收到你的回信，我估计我之前的request被拒绝了。

但是我依然还是希望你能够复查一下我的期末考试试卷，因为我实在是无法相信我这门课考了一个这么低的分数。

我知道也许我因为这件事打扰了你很多次，我对此感到非常的抱歉，但是这个考试的结果对我来说太重要了，这将是我最后一次因为这样的是拜托你。

我将非常的感激if you could do this.

我的翻译：
Dear Professor:

I didn't receive any rely from you. I guess my previous request has been rejected.

But could you take some time recheck my exactly exam paper again, since i really can't believe I got a such low mark.

I Know i maybe bother you too much times about these kind things. I feel truly sorry about this. But this result means too much for me and this will be my last request

I will very appreciate if you could do.
