Start with the cue ball (CB) in position 4. Each time you pocket the object ball (OB), advance the CB one position (e.g., from 4 to 5); and with each miss, move down by one number (e.g., from 4 to 3). If you succeed at position 7 or miss at position 1, stay at that position. The phrase “progressive practice” is used to describe this type of drill because the difficulty level changes progressively in response to your performance.

• Continue for 10 shots total unless you already have a guaranteed score of 10 (e.g., you can stop if you make the first eight shots).

• Adjust the CB position after the 10th shot based on the outcome, but not below 1 or above 7. For example if you make the 10th shot at 6, the final position is 7; and if you miss the 10th shot at 6, the final position is 5.

• Your score for the drill is the final position number plus a bonus for excellence. The bonus is equal to the numbers of successes at position 7. The maximum total score allowed is 10.

• Any drill in this exam can be done from the other side of the table (e.g., if it is easier to reach for a left-handed vs. right-handed player).
