I have searched on the CogAT in prior postings so I am somewhat familiar with what it is supposed to assess but was wondering how it is scored? I am not sure what to tell my DS6 about it. He recently took the WISC-IV and WJ-III ACH and struggles with open-ended questions especially. Is it all multiple choice? Is there a penalty for guessing? Should he skip a question if he is stuck or guess and move on? Just want to know the things I would want to know going into the test.
