- Time myself on one of the exercises in the ALGEBRA PINBALL table below.
- Do at least 20 problems.
- The
*number correct*must be at least 90% of the*number attempted*.

This is to prevent me from just clicking quickly until I get specific problem(s) that I know how to solve. - Print (
`File–Print`) the summary sheet that I get when I press the "End Timing" button.

Or, just look at my time, and if I'm faster, then I'll copy the information into this chart!
