Intelligence levels. Snort. In any case, we’re not talking differential equations here. In a healthy kid with no learning disabilities, the kind of stuff on this test shouldn’t pose a problem for learning. If the kid wants to learn and has a teacher capable of teaching it.
You are deluded. I once taught elementary math and it was scary the level of stupidity/ignorance.
The role of intelligence is irrefutably established in spite of desperate attempts to deny it.
