Cheating in college is not a very good idea.
The truth is, cheating in college is a very bad idea, because the risk of getting caught has been increasing over time, and the penalties for cheating in college are very severe, much more severe than in most high schools, especially public high schools.
It is not an exaggeration to say that
Getting caught cheating in college can set a person's life back YEARS.
This is because almost all colleges and universities have an "Honor Code".
The Honor Code is not some meaningless document or formality that the student is required to sign once and then it is forgotten about.
At many schools the student is required for every exam (and many times also for other assignments) to sign a declaration of their complying with, following, and faithfully upholding the Honor Code by not cheating in college.
The Honor Code is taken very seriously and the penalties for violating the Honor Code by cheating can range from receiving a failing grade on the exam or assignment on which the student cheated, to receiving a failing grade for the course in which the student cheated, to complete expulsion from the school.
Most professors in college are very serious about cheating, and are careful to be on guard against it. Even the "Ivy League," including Harvard University, which is very often ranked as the top or one of the top colleges, has not been spared the plague of college cheating.
In early 2013, about 125 students at Harvard were disciplined for cheating during 2012. Half of those students received the punishment of having to withdraw from school for two semesters (one year), a quarter received academic probation, and the rest received no punishment due to insufficient evidence (Read the Boston Globe's report of the story here).
This report on cheating in college, "Duke: 34 MBA students punished for cheating", describes a big scandal that occurred when 34 students in one class in the MBA program at the School of Business at Duke University were caught cheating.
Shortly before that, 122 students in undergraduate physics were caught cheating at the University of Virginia, which has been described as having one of the strictest honor codes.

One of the many tools that tips the balance heavily in favor of the professors and against college students that cheat is the service provided by turnitin.com.
That website allows the comparison of all of the papers submitted for a class assignment to be compared to each other, as well as to text that is available on the internet.
So professors can tell, using that service, if students copied each other's work or sources on the internet.
There are many other similar services offering software to detect and discover cheating and plagiarism, and the list of those services and software programs is growing.
Cheating in college is simply not worth the risk, especially since it is possible to honestly do well in the race for good college grades.
