Hi, if you go to the OPC website, they do the type of industry tests for TOCs. You can try the practice tests they have.
Essentially the SCAAT is a repetitive test that has you crossing out a set shape(s) /letter(s) from a block, going from left to right. The first test is a one shape, the second is two shapes and the third is one set shape and one changing shape at the start of each line.
