<p>This should hopefully be obvious to most prefrosh, but I’ll say it anyway: If you see links to tests/quizzes/answers on the course website for a class you haven’t taken and that you have any chance of taking in the future, don’t look at them! Lots of times questions are reused for tests and quizzes. Lectures notes and lecture slides are almost always fine. Syllabuses are definitely fine. Problem sets are questionable. It’s not a big deal if they reuse the problem sets year after year (as long as you don’t look at a solution set), but it’s conceivable that some profs might use some previous year’s set questions as the basis for test questions. If the set questions are in the book it’s probably fine, but in other instances, I would email the professor to check.</p>
<p>On that note, if you ever accidentally violate the honor code, contact the professor or head TA as soon as possible, and they’ll almost certainly find a fair solution for you without having to involve the Board of Control or auto-failing you. The easiest way to avoid accidentally violating the honor code is just to read test instructions very carefully. You usually get a chance to read the cover page of an exam long before you take it, so read it multiple times. Make sure you know how long it is, what materials you are allowed to use, whether or not breaks are allowed, etc.</p>
