We know that the SAT includes questions that don't affect your score, they have some new 'trial' questions which they are checking to see how people do on, and some will become scored questions in the future. Actually, at least at one time, I think the SAT included one whole section like this, that is, there everybody took 5 parts but one of them had only 'trial' questions. OK, OK, maybe somebody will tell me they don't do this any more, I took the SAT about 40 years ago.
Does anybody know if Cisco does the same thing? It doesn't really matter, except it might explain why I thought I was doing worse than I really did, if many of the questions i thought I got wrong were these experimental ones and didn't affect my score.
