Divide 36 golf balls into 3 groups of 12 balls. Put each group in the rough near the green.

On the green, mark 3 target zones about 15 feet from the rough.

Hit bump-and-run shots, aiming for each of the 3 zones in order. Hit 12 shots at zone 1, 12 at zone 2, and 12 at zone

Each ball that lands and stops inside its target zone counts as a success.

Get 36 golf balls and split into 2 groups of 18 balls each.

Put one group of 18 balls on the uphill slope, close to the green.

Put the second group of 18 balls on the downhill slope, about 5 yards from the green.

On the green, set up 3 target zones in a line, about 6 feet apart.

From the uphill pile, hit 6 shots at each target zone (first at Zone 1, then Zone 2, then Zone 3).

From the downhill pile, hit 6 shots at each zone in the same order.

Ball counts as a success if it stays in the chosen target zone.

Make 10 piles of 4 balls (40 balls) in two lines, crossing each other near the green, 1 to 10 yards from the green and 5 to 30 yards from the hole. Keep piles 2 yards apart, lines 5 to 10 yards apart.

On the green, use string or tees to mark two circles around the hole: one with a 6-foot radius (inner), the other with a 15-foot radius (outer).

Use only 36 balls (9 piles of 4) for this test.

Split the 36 shots into two groups of

For the first 18 shots, try to land the ball inside the small circle.

For the next 18 shots, try to land the ball inside the big circle but outside the small circle.

Play bump-and-run shots by hitting from different piles, one after the other, keeping the same setup and order.

Count as a success if the ball stops in the correct circle. If not, it is a miss.

Count how many balls finished where they should in both circles. Enter your score in the app, out of 36 attempts.

Set up two lines of 18 golf balls each on a sloped fairway near the green: one line on the uphill slope, one line on the downhill slope. Balls should be spaced 5 yards apart, between 5 and 30 yards from the hole.

Place 3 target zones on the green in a row, 6 feet apart. Call them Zone 1 (closest), Zone 2 (middle), and Zone 3 (farthest).

Hit 36 total bump-and-run shots: 18 from the uphill line, 18 from the downhill line.

From the uphill line, hit 6 shots to each zone (6 to Zone 1, 6 to Zone 2, 6 to Zone 3). Always hit every third ball, skipping two balls between shots.

For the downhill line, repeat the process: 6 shots to each zone, using every third ball.

Count a success each time a ball stops inside the intended target zone.

When all 36 shots are done, record how many balls landed in the correct zone, out of 36 attempts, in the app.

Put two rows of 18 balls each on grass near the green. Keep the rows 5 yards apart.

Put both rows about 10 yards from the hole.

Make three target zones on the green: Left, Center, and Right. Each is about 4 feet wide.

There will be 36 bump-and-run shots: 12 for each zone.

From the first row, hit every third ball to the Left zone (12 shots).

From the second row, hit every third ball to the Center zone (12 shots).

Go back to the first row. Hit every third ball to the Right zone (12 shots).

Count the shots that stop inside the target zone.

Arrange 10 piles of balls in two lines, with 5 piles in each line. Lines are 3 yards/meters apart; piles are 4 yards/meters apart in each line.

Put the piles on grass, 1 to 10 yards/meters from the green and 5 to 30 yards/meters from the hole.

On the green, make two target circles with string or tees: an inner circle with a 6-foot/2-meter radius, and an outer circle with a 15-foot/5-meter radius.

Hit 36 bump-and-run shots: 18 shots at the inner circle, 18 shots at the outer circle.

Pick a ball pile and hit a bump-and-run shot to the target circle.

After 18 shots at one circle, switch and do 18 shots at the other circle.

Count every shot that stops inside the target circle as a success.

Arrange 40 balls into 10 piles of 4 balls each. Place the piles in two parallel lines, 5 to 10 yards apart, with each pile in a line about 2 yards apart.

On the green, mark two target zones: an inner circle with a 6-foot radius and an outer circle with a 15-foot radius.

Hit 36 shots: 18 to the inner circle, 18 to the outer circle.

Hit shots from any pile, switch between piles and lines.
