How to Break 100 in Golf

A score of 99 or lower for 18 holes is the line. Under the Rules of Golf, a gross score counts every stroke made and every penalty stroke, so both belong on the card. You do not need a round full of birdies to get there. You need fewer holes where the score runs away.

On each hole, write four things: the score, any penalty strokes, the number of putts, and, if the hole went badly, a word for where the trouble started. Across the round, keep three tallies: penalty strokes, three-putts, and holes of triple bogey or worse. Written down, a pattern is easier to check than a memory of how the round felt.

Then pick a reference line and keep it the same from round to round. The example below uses one over par on every hole. On a par-72 course, a bogey on every hole adds up to 90, which leaves room for nine more strokes and still breaks 100. The line is for counting, not a target for each hole.

Record penalties as you actually took them. A course’s Committee may adopt Model Local Rule E-5 from the R&A’s Model Local Rules, which lets a player whose ball is lost or out of bounds take relief in an area based on where it was lost or went out, for two penalty strokes, instead of going back under stroke and distance. If you used it, write 2. The R&A says it is not appropriate for competitions limited to highly skilled players, so check the Local Rules before assuming it applies.

This is not an instruction to ignore your swing. It is a way to decide where a swing lesson, practice session or course-management change can actually help. A shot that stays in play gives you a chance to make the next decision. A penalty stroke removes that chance and adds to the card immediately.

The round below is invented for this guide. It is not a real player’s card. The fictional golfer shot 104 on a par-72 course and wanted to know where the strokes went.

Step 1: the three tallies. Five penalty strokes (holes 4, 8, 12, 15 and 18). Four three-putts (holes 1, 8, 13 and 15). Four holes of triple bogey or worse (holes 4, 8, 12 and 15). These are counts of events. They show what keeps happening, and they are not meant to be added together.

Step 2: the double-counting trap. Suppose the golfer adds the five penalty strokes, the four three-putts and the ten strokes the four big holes went over the line (2, 2, 3 and 3). That gives 19. But the ten holes that went over the line went over by 16 strokes in total, so 19 cannot be right. Holes 8 and 15 sit in all three tallies, and some of their strokes have been counted two or three times.

Step 3: split each hole once. Give every stroke over the line to one cause, and check that each hole’s parts add up to its total.

Hole 4 shows how a penalty is counted once. Out of bounds means stroke and distance under Rule 18.2b: one penalty stroke, then the next shot is played from where the last one was made. The penalty column shows 1. Compared with a tee shot that stayed in play, the hole is two strokes worse on paper: the shot that went out and the penalty stroke. Both go to “tee shot” in the split, and neither is added again anywhere else. Holes 8 and 18 count 1 each for their tee shots: in this example, relief from the penalty area left a similar next shot, so only the penalty stroke is counted.

Hole 15 shows why the cause matters more than the column. Its penalty stroke came from a shot through the trees that went out of bounds, so it is filed under recovery, not tee shot. It is still one of the five penalty strokes on the card. It is simply not counted a second time.

Step 4: add up the causes and check the arithmetic.

• Tee shot: 6
• Putting: 4
• Recovery: 3
• Around the green: 3

That is 16, the same as the strokes over the line on the ten holes that went over. Holes 5 and 11 were pars, one under the line each. So the whole card checks: 90 + 16 − 2 = 104. If your own causes add up to more than your strokes over the line, something has been counted twice. If a stroke does not fit any of the four causes, write it as “other” rather than forcing it in.

Step 5: read it carefully. In this round, tee shots started 6 of the 16 extra strokes, more than any other cause, and putting was next with 4. On paper, without those six strokes the card would read 98. That is arithmetic, not a forecast: a tee shot kept in play still has to be followed by ordinary shots. One round is also a small sample. Review two or three cards the same way before changing a practice plan.

Different cards point to different practice. The three priorities below match the main causes in the review. None of them is right for every golfer, and the practice tests are examples to adapt, ideally with a qualified coach.

1. When tee shots start most of the extra strokes. Before the round, mark the holes where a penalty area or out of bounds sits within reach of your usual miss, and choose a tee club for each. That can still be driver where the hole has room. In practice, set two markers about as far apart as a fairway you play is wide. Hit the clubs you plan to use off the tee, change club and target between balls the way you would on the course, and score each ball in or out. Keep the count from session to session.

2. When recovery choices start them. Write a rule for trouble before the round, for example “from trees or a bad lie, the next shot goes to the widest short grass I can reach in one stroke.” In practice, play low, controlled shots to a wide target and count how many reach it in one stroke. If bunkers are the trouble, the first test is getting out in one. Hit from rough, slopes or bunkers only where the facility allows it, with nobody in front of or close to you.

3. When they start around and on the green. Split the time between long putts and short shots around the green. From long range, count how many putts finish inside a zone around the hole that leaves an easy next putt. From a few different lies off the green, count how many chips or pitches finish on the green in one stroke. Three-putts and chips that stay short or run across the green are separate problems, so keep separate counts.

Whichever priority the card points to, give every practice session a simple test. Pick a target, vary the lie or distance, and keep a small score instead of hitting the same shot until one looks good. If two causes are close, or the leading cause changes from round to round, review another round or two before choosing, or take the cards to a coach.

On a hole where driver brings a clear penalty area, trees or out-of-bounds into play, choose the club that gives you the widest playable next shot. That may still be driver. It may be a fairway wood, hybrid or iron. The point is to choose from the hole in front of you, rather than from the club you think you are supposed to hit.

A conservative tee choice is not a permanent strategy. It is a scoring strategy while you learn which misses cost you the most, and the scorecard review shows you which holes those are. If you want a deeper way to think through targets, read the course-management guide.

A ball in trees, deep rough or a poor lie is where a bogey can turn into a large number. The useful question is not “can I pull off the hero shot?” It is “what shot puts the next one somewhere ordinary?” Punching back to grass, laying up short of trouble or pitching back to a full swing can keep the hole alive. Hole 15 in the example shows the other path.

The Rules of Golf govern relief. A ball in a penalty area may be played as it lies, or you may take relief for one penalty stroke under Rule 17.1. Anywhere else on the course, you may choose the applicable unplayable-ball relief under Rule 19. Its normal options cost one penalty stroke; bunker options have specific limits, and the extra back-on-the-line option outside a bunker normally costs two. Check applicable Rule 25 modifications and the course’s Local Rules too. Do not invent a free drop because a lie feels unfair.

Before the next round, write one rule for the day, taken from the cause your cards point to: for example, “no risky recovery through trees,” or “pick a target before every tee shot.” Keep it narrow enough to remember on the ninth hole. A score goal is easier to use when it becomes a decision goal you can apply before a shot.

Once 99 becomes repeatable, the next job is turning bogeys into pars and removing the doubles that remain. Continue with how to break 90.

Before the round

• Bring the last two or three cards, or their tallies.
• Read the Local Rules on the card or notice board, including whether the two-stroke drop for a lost ball or a ball out of bounds is in use.
• Mark the holes where a penalty area or out of bounds is in reach of your usual miss, and choose the tee club for each.
• My rule for the day: ________

On every hole

• Score, counting every stroke made and every penalty stroke.
• Penalty strokes, as you took them.
• Putts.
• If the hole went over the line, one word for where it started: tee shot, recovery, around the green, putting or other.

After the round

• Strokes over the line, on the holes that went over: ________. Strokes under the line: ________.
• Split: tee shot ________ recovery ________ around the green ________ putting ________ other ________. These must add up to the strokes over the line.
• Check the card: the line, plus strokes over, minus strokes under, equals the score.
• The cause with the most strokes, and whether it matches the last two cards: ________
• One practice priority and one rule for the next round.

The process works the same way for a junior, with the player doing the counting. Let the player keep the card, choose the reference line and pick the one rule for the next round. Ask what happened on a hole before offering a cause, and talk about the card (“the tee shot on 4 started two strokes”) rather than about the player.

Breaking 100 is a general-golfer milestone, not an age target. A junior playing nine holes, forward tees or a shortened course has a different card. Review the holes actually played, on the tees actually used, and compare a round only with earlier rounds on the same course and tees. Do not double a nine-hole score to compare it with 100. If long holes keep going over the line even when nothing went wrong, the tees may be the question rather than the practice plan. For a longer record across a season, see how to track a junior golfer’s improvement.

Keep it light. For a newer player, one tally the player chooses is plenty, and the full split can wait until counting feels easy. Let a qualified coach adjust any practice test to the player’s size, strength and physical needs, and supervise practice wherever balls are being hit.

In ordinary individual competition, keep the advice review until the round is over. Under Rule 10.2a, during a round a player must not ask anyone other than their caddie for advice. Partner and team formats have specific permissions under Rules 22–24. Check the event’s own rules on caddies and spectators, and read the parent rules and etiquette guide before the first tournament.
