In October, a student got a 96 on his precal test. Sweet. At a private school. A really good one.
Another student got an 84. But he needs to be neater: he read his own written y as a 4. And he did not, I think, do the extra work I suggested he do. He made some mistakes on the test, mistakes he should not have made. He knew better.
Practice, practice, practice. Drill, drill, drill. As they do in sports, dance, and music.
