Ad1, our correspondence reminds me of an old friend from high school. He tutored me for free to get me ready for a Trig Exam. I asked him why he did it? He said it helped him to formulate the material in his mind as final preparation for the test. It showed him the areas where he was weak. So that night all he had to do was brush up on what he didn't know for the exam. He also said by doing this he didn’t have to study as much because he only had to go over what he didn't remember. As it turned out I wasn’t the only one he helped. By tutoring friends, mostly girls, he adapted a fun way of learning while teaching others. He knew how to take the drudgery out of studying. He is now a medical doctor.
I'm not comparing myself to him, only remembering how he made learning easy. As it turned out the guy made extremely high scores on his SAT's. He always anticipated the teacher's questions before they could get the last word out. You know the type, the teacher's pet. There's not many people around like that but I do admire his learning tools he passed down to me. Maybe there's something here we can all learn from.
