Out of my Expectation...

Here's the bad news of today:
1) I tried as hard as I could to finish the Biology and Chemistry tests within the time limit, though it was in vain.

2) I received my marked English composition, which was the first composition I wrote in this term. The result was unexpectedly unsatisfactory. Which is what made me blue for the rest of the day.

With barely any preparation, there's nothing I could blame for. Or that's myself if there's any. It was me who didn't pay much attention on the test and take it serious for ever. I kept chatting with friends and went for a film even when I knew the tests were ahead. I realised that I myself lacked self control all along, and I made no effort at all to fix that. Instead I just let this go on. It was with no doubt that I had entirely overlooked the consequences of lacking self control. It kills. Hopefully, it's not too late to collect myself and equip myself for one of the fatal, all-or-nothing moments, i.e. The HKCEE.

Well so that's all I'd like to talk about the tests.

So what about my shitty composition?

Yea, I did devote myself in the composition when I wrote this, which took me forever to have it done. I always take composition homework seriously and expect something out of it. I, however, missed for once and immediately felt totally down. Being frown, I found myself hard to concentrate on the lessons.

Be that as it may, the unsatisfactory result alarmed me that I have to work harder in all aspects and not to be blinded by my own ego.

In all, I regard it as a warning delivered by God to remind me that one wrong step may bring a great fall.


BTW, I got stuck in a M.I. question:

Please prove that (2n)! >= (2n)^n for all natural numbers n.
Leave me a solution should you know the answer.
Thanks.
