Judy - reasonable intelligence, common sense, critical thinking...
Actually, I don't ALWAYS know when a loved one is being honest. I lived with a habitual liar, my ex husband, and it was hard to discern when he was telling the truth. Most of what I learned was that I chose to trust my gut feeling, and not base it on intelligence, common sense or critical thinking. That didn't work.
Didn't I read somewhere that some kids choose to do one course at a time as opposed to doing several? If that wasn't his choice, then the academic advisor may have seen a need to do it this way. I get that you questioned the lesson plan, but that may not be the whole story.
