cheating is a significantly common occurrence in high schools and colleges in the United States. Statistically, 64% of public high school students admit to serious test cheating. 58% say they have
plagiarized. 95% of students admit to some form of cheating. This includes tests, examinations, copying homework, and papers. Only 50% of private school students, however, admit to this. The report was made in June 2005 by

Sport, games and gambling
Sports
Cheating in sports is the intentional breaking of rules in order to obtain an advantage over the other teams or players. Sports are governed by both customs and explicit rules regarding acts which are permitted and forbidden at the event and away from it. Forbidden acts frequently include performance-enhancing drug taking (known as "
doping"), using equipment that does not conform to the rules or altering the condition of equipment during play, and deliberate harassment or injury to competitors.

High-profile examples of alleged doping cheating include
Lance Armstrong's use of

Athletic cheating is a widespread problem. For example, in
professional bodybuilding, cheating is now estimated to be so universal that it is now considered impossible to engage in professional competition without cheating and the use of supposedly banned substances; bodybuilders who refuse to take banned substances now compete in
natural bodybuilding leagues.
Cheating may also be seen in
coaching. One of the most common forms of this is the use of

.
An example of cheating via judging collusion occurred in the
2002 Winter Olympics figure skating scandal when the Russian team was awarded a gold medal over the Canadian team in an alleged vote-swapping judging deal; the Canadian team's silver medals were eventually upgraded to gold at a second awards ceremony and the French judge was suspended for misconduct. The head of the French skating federation was later also suspended, and both were banned from the 2006 Olympic Games. The
International Skating Union modified its
judging system as a result of this case.
Cheating is also used to refer to movements in
strength training
Strength training, also known as weight training or resistance training, is exercise designed to improve physical strength. It is often associated with the lifting of Weightlifting, weights. It can also incorporate techniques such as bodyweigh ...
that transfer weight from an isolated or fatigued muscle group to a different or fresh muscle group. This allows the cheater to move an initial greater weight (if the cheating continues through an entire training set) or to continue exercising past the point of muscular exhaustion (if the cheating begins part-way through the set). As strength training is not a sport, cheating has no rule-based consequences, but can result in injury or a failure to meet training goals. This is because each exercise is designed to target specific muscle groups and if the proper form is not used the weight can be transferred away from the targeted group.
Video games

In video games, cheating can take the form of secret access codes in single-player games (such as the
Konami code) which unlock a bonus for the player when entered,
hacks and exploits which give players an unfair advantage in online multiplayer games and single-player modes, or unfair

Attitudes towards cheating vary. Using exploits in single-player modes is usually considered to be simply another form of exploring the game's content unless the player's accomplishments are to be submitted competitively, and is common in single-player games with a high difficulty level; however, cheating in multiplayer modes is considered immoral and harshly condemned by fair players and developers alike. Cheating allows casual players to complete games at much-accelerated speed, which can be helpful in some cinematic or single-player games, which can take a subjectively long time to finish, as is typical of the
role-playing game

(RPG) genre. While this may be seen as a hasty advantage causing no damage to anyone, in a multi-player game such as
MMORPGs the repercussions of cheating are much more damaging, breaking the risk/reward curve of the game and causing fair players to lose online matches and/or character development. Cheating in those types of games is generally prohibitedthough often widespread anyway. In many circles, the purchasing of items or currency from sources outside the game is also considered to be cheating. The
terms of service from many games where this is possible directly prohibit this activity. One area where there is little consensus involves modern
free-to-play business models which support and are supported by the exchange of real-world money for in-game services, items, and advantages. Games that grant excessive advantages only available to paying customers may be criticized as being 'pay to win'sometimes considered a form of "cheating" that is actually legitimatized by the systemwhilst games that limit real-money purchases to cosmetic changes are generally accepted as fair.
Another form of video game cheating is when a player does things to interact with game objects that are unforeseen by the programmers and break the intended function or reward system of the object. This can involve the way enemies are encountered, objectives met, items used, or any other game object that contains a

. One common example is the exploitation of errors in an enemy's
pathfinding; if a player can cause an enemy to become "stuck" in a given terrain feature, that player can then usually kill the enemy from a distance without risk, even if much stronger, and achieve greater rewards than the player is intended to be able to at that level of progression. Another example was common in early

games and involved skipping a weapon's reload timer by quickly switching weapons back and forth without actually reloading the weapons, resulting in what was effectively instant reloading. It also can be accomplished through means of altered game files substituted for the normal files, or image graphics changed to permit greater visibility of the targets, etc.for example, replacing the colors on a dark-colored enemy intended to blend in with the background with a bright color permitting instant visibility and targeting. Generally speaking, there is often some concern that this is not truly cheating, as it is the fault of the programmers that such an exploit exists in the first place. However, technically, as with live sports, it is cheating if the player is not playing the game in a formally approved manner, breaking unwritten rules. In some cases, this behavior is directly prohibited by the terms of service of the game.
Gambling

The wagering of money on an event extends the motivation for cheating beyond directly participating competitors. As in sport and games, cheating in
gambling
Gambling (also known as betting or gaming) is the wagering of something of Value (economics), value ("the stakes") on a Event (probability theory), random event with the intent of winning something else of value, where instances of strategy (ga ...

which plays with secretly
loaded dice, a rigged
roulette wheel or

may be regarded as
salesmanship rather than cheating, since bettors can counter this by informing themselves and by exercising
skepticism.
Doping a horse is a clear example of cheating by interfering with the instruments of the event under wager. Again, not all interference is cheating; spending money to support the health and well-being of a horse one has wagered on is not in itself generally regarded as cheating, nor is improving the morale of a sportsman one has backed by

for them. Generally, interference is more likely to be regarded as cheating if it diminishes the standard of a sporting competition, damages a participant, or modifies the apparatus of the event or game.
In the world of gambling, knowing a secret which is not priced into the odds gives a significant advantage, which may give rise to a perception of cheating. However, legal systems do not regard secretly making use of knowledge in this way as criminal deception in itself. This is in contrast to the financial world, where people with certain categories of relationship to a company are restricted from transacting, which would constitute the crime of
insider trading. This may be because of a stronger presumption of equality between investors, or it may be because a company employee who also trades in the company's stock has a conflict of interest, and has thus misrepresented himself the company.

, whose legislation is uniquely influenced by large casino corporations. Nonetheless it remains a widely held principle that the law should not impose any restraint over the method by which a player arrives at a playing or betting decision from information held by him lawfully and which he is not debarred from under the rules of the game. In "hole carding", a casino player tries to catch sight of the front of cards which are dealt face-down according to the rules.
One way of cheating and profiting through gambling is to bet against oneself and then intentionally lose. This is known as
throwing a game or taking a dive. Illegal gamblers will at times pay sports players to lose so that they may profit from the otherwise unexpected loss. An especially notorious case is the
Black Sox Scandal, when eight players of the 1919 Chicago White Sox took payment from gamblers and intentionally played poorly. Another happened in
