I've been studying up for a skills assessment test that I must take ASAP for a possible job interview and the level2 switch challenge is giving me fits. Easy enough to figure out the level1 tests but level2 ... I get 4,1,3,2 and that's not an option. After the top row runs through the 1342 filter the objects are then arranged square, triangle, plus, circle. To result in the bottom row outcome would need a 4132 filter. Now if the original values of square1, circle2, triangle3, and plus4 are retained throughout the first filter, I get 2143 for the second filter. ???
