Actually, the only thing I am concerned is:
1) the thickness of the pen-it matters if the pen is so thick that not only it occupies white board space but also it is not easy to be used for heavy calculation.
I tend to do a lot of calculation in math and do find it faster than some techniques such as plugging in or POE. If the pen is too thick then i might need to change my way taking math.
I heard the board is 8 x 14 legal size... I will purchase the pen today and start practicing.....
I just don't get it though, to prevent someone recording any GMAT questions on paper, they may just used thicker paper or thin cardboard so that the paper/board size is big enough to sneak it out of the test center. In this case, people can still use regular 0.5mm ballpen. Why do they have to change both the pens and paper which gives a headache for many test takers (from what I have been told)??? No one is going to erase any writing during the test anyway.... arghhh!
At last, thanks for the info!!!
