Test 1 concerns spatial judgment. The rules are to simply place shapes in the box and create a full square out of them. Not all pieces are needed to complete the shape, and it can be challenging, including very thin pieces as part of the puzzle. The quickest solution to the test is most likely putting in the corner pieces first, then the larger ones, and then adding the minor ones. The test is a tangram, forcing you to fit as many as needed of the pieces given into the shape of a rectangle. There are multiple versions of pieces.
