<p>A lot of professors automatically post practice midterms/finals (which turn out to be the previous year’s exams), but if they don’t, I think it’s perfectly reasonable to ask if they might post some practice problems. And most professors will definitely inform you of the format of the exam before you take it, so you don’t have to worry about that. Even in my most disorganized classes, professors have provided practice exams. </p>
<p>Don’t worry too much about this stuff now, though. The prospect of taking a college exam will be far less daunting when the time actually comes. And even if the professor doesn’t specifically provide past exams, I’m sure you’ll be able to figure out how to study.</p>
