<p>At the universities where I’ve been teaching we are ALWAYS happy to answer questions . However profs don’t have their own classroom and space is in constant use so we can’t stay and chat the way it’s done in high school, where in addition students can return to the classroom after the last bell and be quite sure the teacher will be there. overall that’s why office hours are so important. On literally hundreds of mid semesters self evaluations '/‘what I wish I’d known’ the top ones consistently include having a writing center tutor review your first paper in each subject and attend office hours right away to prevent problems rather than waiting the midterm or the first grade.</p>
