Level 2 works different from level 1. For level 2 you have to choose the one before the last one. If it goes from letter P to C then to P again you have to pick that it is the same sound. The same applies to the location of the squares. I am not sure about level 3, I am going to start doing that one soon.

Level 3 has the same system as level 2, which means that that if P is the first letter, G is the second and P is the third, you have to choose that you heard the same letter. Level 3 simply has more trials. So in terms of the system, only level 1 and 2 are different. From level 3 onwards more trials are added. Also see: http://brainscale.net/dual-n-back/tutorial

What I wrote last time is wrong. If you have completed level 2 with a score of 90% or more, in level 3 it is 3 letters and squares before the current one. So the correct answer in level 3 is 3 letters and/or squares before the current one, unless you completed level 2 with less than 90% correct. You can test whether it is 2 or 3 letters/squares.
