So if you're right-handed, you're probably totally unaware of the writing woes that left-handers deal with; due to the left-to-right nature of the English language, left-handers have to write very carefully or risk smudging their writing.
I was thinking this might be particularly problematic with the laminated testpads and markers, since I can imagine the pad/marker combo is significantly less permanent than the paper/pen combo.
Have any lefties taken the GMAT who can confirm/deny whether this is an issue with the pens/pads.
PS I'm mostly kidding about the 'writing woes', but in this situation it might be a legitimate concern.
