Can you use someone else's essay from another school as your own work, with proper citation, while attending college?

Yes you can use someone else’s essay in college, and you will violate the academic honesty policy and be subject to a variety of consequences including expulsion.

First, ethically presenting work that is not your own is not appropriate. Imagine that a loved one needed surgery, and the surgeon did not do their own surgery in medical school.

Second, most schools use tools that look to see if an essay has been used at other schools. It will be pretty obvious what you have done.

Third, faculty can often tell when a student is submitting something that is not their own work.

Yes you can do it, but it is not a good idea.
