What makes this different?
Unlike Levels 1–4 which drill one operation at a time, Level 5 interleaves all 18 operations on every page. The brain must retrieve the right fact from any of 18 possibilities — true automaticity.
How to use it
Same routine as always: fill in Name, Date, Start time, then go. Mark when done. Aim for under 2 minutes per side. Repeat the same day's sheet on Side B to push for speed improvement.
