When you wrote your essays in the exam of english last year shinny and other 2008er's,
did you have chunks of writing crossed out maybe a paragraph and then sometimes writing on top.
because if im a marker and working at 12am marking exams, I wouldnt really like the sort of messy essays so i've heard.
especially when writing a conclusion it wouldnt be ideal to have crossed out sentences because it would look all jumbly.
I'm not a 2008er but in my exam I crossed out half a paragraph, decided to leave it, finished the rest of the essay, went back to it and didn't like it, wrote out another chunk of text on the blank (un-lined) page next to it, and drew a massive arrow with bright pink highlighter to show the examiner where to look. It probably pissed my examiner off a bit but my mark didn't seem to be too affected.
But do the high achievers in english, formulate their full sentences in their minds first before writing? I don't do that but I wish I could.
And if you count me as a "high achiever" - no I don't formulate sentences in my mind before I write. It kind of comes to me
as I'm writing. I don't really know how to explain it. Maybe my subconscious pre-formulates the sentences? But all I usually have in my mind is my argument and the rest just comes out. Which is why sometimes I tend to ramble a bit.

So,
If you can't do that, you can't get your speed at a reasonable level, and speed=necessary for the top scores in English.
I don't think that's true. I still got a decent amount of words without ever formulating any of my sentences prior to them going on the paper.
