Well, my essay is about 1200 when i assemble it together, because I have all four prescribed, 2 stimulus and 2 related prepared, but only write on 2 prescribed, one stim and one related in the exam unless otherwise asked for.
But as for length... my writing is messy unless I write big and clear so it can be read. I've got some print outs of exam book pages and it takes me about 20 of those pages maybe more to write (they are quite big spaced lines in those books so don't get worried it's still the same 1200 words)
But it doesn't matter. The markers can tell how substantial in length the response is by the time it takes to mark. If 3 pages of 1200 words takes them 25 minutes and 20 pages of another person's writing takes 25mins then they realise that its the same.
The whole "lots of pages" refers to people who write 3 pages in huge handwriting like mine which amounts to little over 400 words and no huge insight or substnatial dicussion of the journey.
Don't be stressing about this now... get down and learn the material !
