      Business outlook

      Pros

      Test was moderate level. 4 tests, verbal reasoning, sequencing, mechanical, decision/solutions on total random stuff. Tests are kept on file for a year pass or fail.

      Cons

      Total random subjects in one of 4 of the tests. Must be quick to answer.
