<p>Personally, I prefer pencil and paper. Always have. I usually only use my computer to type up papers or look for assignments, as well as communication (email, skype, facebook, etc).</p>
<p>I’ve never seen a laptop in a math class, very few in science lectures, but they’re pretty usual in humanities classes. I was asked several times in my English seminar last semester to make sure to bring my laptop on certain days. I think it depends on the person, the class, and the professor.</p>
