Drills
One skill. Then the next.
554 drills plus quick-math sprints. Speak or type. Compare to the model as often as you want. Official grades are 3 a day for your first 3 days.
A drill is one prompt and a score. The grade is the equation, the so-what, and whether you stopped. Worked examples sit on the public rooms — start with structure, or the full case method.
