I'm gonna face the CET4 exam a few hours later.
I've got full confidence in my English abilities, but my biggest enemy is my sleepiness.
I tried to force myself asleep last night at around 10 PM, but somehow I ended up waking up at 0:30.
I'm afraid that I'll wake up too late if I kept on sleeping, so I tried to stay awake.
So here I am, half past 2 in the morning.
I hope I won't get too sleepy when the exam comes at length.
