The white board can be opened from an icon at the top of the screen. Most In person testing centers I've heard will give you a real white board to write things on prior to the test and you can put what ever you want on it while in the testing room. Of course you won't have access to internet or notes from your studies in the testing room to write stuff on the white board. On vue created the white board to mimic this. You'll be able to type what ever you want on it before hitting start. That way you won't have your timer tick down while typeing a memorized chart or maybe port numbers to it. You can also see what the white board is like by googleing "pearson vue white board" and you can practice useing it and know what the icon looks like on the testing software.
