We were forced to prepare this podcast after realizing how poorly candidates prepare for the arithmetic rigor they need to display. For some reason candidates believe practicing hundreds of math problems make them better at math. This is not how to learn math in cases. This podcast gives you proper guidance on learning arithmetic for cases, and how to communicate this competency.
Do not merely try to be fast with a bad math technique. If you fix the technique, the underlying problem, your speed with naturally improve.
