<p>At UVa, many professors make students sign an oath under the Honor System that they have not looked at old tests. </p>
<p>They have thrown out students who copied computer code for a programing class from a previous student.</p>
<p>In any case, a prof should be smart enough to change their tests around every year.</p>
<p>If a student relies upon a test bank, they will really get hit upside the head when the prof hands out a test that wasn’t in the test bank. That is because the student will not have learned the material throughout the year. Or, they will flounder the next semester when they didn’t learn the material that it is based upon.</p>
