This is great advice. Particularly, your paradigm of 'not being able to score 800 w/o writing everything down is extremely powerful'
However,
1) I have seen that I really have to write down everything if I have to almost completely eliminate silly errors. I even have to write down simple arithmetic steps as thats where I make most of the mistakes e.g. adding 12+5 to 19 instead of 17... like really nasty random silly errors. That doesnt mean that I am immune to other forms of silly mistakes such as not flipping inequality while multiplying by a negative number or not distributing the negative sign through a parenthesis in a hurry etc. So writing everything down doesnt come without compromising speed at least to me.
2) I am not looking to score 800 really. I scored 750(48Q+46V) in my previous attempt w/o writing much during the exam. I didn't even put pen to paper during the verbal section. I am looking for a modest improvement of 20 points+ 2points improvement on quant section. So my target is 770 with at least 50 on quantitative section.
Ok you might ask - 'why be so adamant about not writing?' It's a personal tale of my struggles with writing throughout my academic career. I suspect I have a mild or limited case 'dysgraphia', which is probably limited to the physical act of writing and organizing thoughts on a topic. Also, the slipper scratch papers and special marker provided during the exam really don't help my condition.
Would you still advise me to write everything down even if I am just looking for an improvement of 2 points on quant section esp when its going to be such a huge task to be able to write everything ? Or there is no exception- I should do whatever it takes to work around my writing troubles if I ever hope to achieve Q50?

almost no one believes me when i first tell them this, but then about 90% of the skeptics come back wide-eyed with astonished declarations of "you were right!":
performing routine processes mentally, rather than on paper, will SLOW YOU DOWN.
the more steps you write down, the FASTER you will execute the process.
this holds for pretty much everything - factoring, AD/BCE, eliminating answers, charting RTD problems, defining variables, etc. about the only exception that comes to mind is VERY simple arithmetic; there's no need to write down, say, addition and subtraction of one- and two-digit numbers. BUT YOU SHOULD WRITE DOWN EVERYTHING ELSE.
the other thing of which you should be aware is that the mental processes will work, most of the time. this is more than a bit ironic: the reason that the vast majority of students don't want to write steps down is that NOT writing them down usually works.
let's say that mental processes get you correct answers 85%, or even 90%, of the time.
what you've got to realize, though, is this: writing down the steps will ensure correct answers 99+% of the time. if you're just working practice problems, that's not that big of a difference - but i wouldn't want to bet gmat points on an 85% or 90% sure thing.
write down everything.
