Yesterday there were three major motor sports races. I imagine if the three winners where to attend a high school drivers education class they might decide that it was tedious and no fun. Repetition is for boneheads to make sure they remember, not for people who are already experts.
The majority of people do not think math is fun. They will not willingly do it. For others it's writing, or science, and for others, PE. For a balanced education students must understand that learning is necessary work, even if it is not fun.
We spend hundreds of billions trying to educate our children with spending tripling since I started school in 1958. Somehow despite these efforts students receive less education now then students did 100 years ago.
