Apparently you're supposed to start the essay with a hook. A personal hook.
Try this:
" My life sucks" or maybe "there's no bigger loser than one who reads about loser. guess that make you one.."

Or whatever.

I'm really not in the mood of stressing my poor soul any further. Instead what I really yearn to do is to get bloody, and to rip up my head and with bare hands remove the blockage in my brain and juice it before i empty it into the nearest drainage system.

Stress and angst frustration have fill my lungs to its brim as I can hear the invisible clock ticking behind my shoulder. Time slips by like the passing wind, leaving with little but doubts and regrets.

I swore to NEVER go down without a worthy fight this time.

But like never before, (emphasis: never before) the demons within and in the external worlds unite to test the very limits of my determination and inconsistent persistence ( a paradox, I know)

The many rules and laws of grammar, of structures, or SAT methodology swimming in my clouded head with vague statements that nag at my every phrase or word. The pencil resists the mental flow of my words, refusing my pleas to facilitate thought and writing. Mentally, I shouted "Shut Up" only to hear reverberations of more nagging revisions or work obligations. My bid to the maddening noise lost to me in the noise I seek to silence.

Repeat to me: your english is not that bad. And say this again: You have a mind of your own and sound opinions. Lastly: you are not an ITE student. Oh! I forgot: the 25 minutes you have is over. You fail this essay once more.
