Will students only be in huge lecture halls?
Some of your classes might be in huge lecture halls, but some schools don't even HAVE huge lecture halls, so it really depends on the institution. If a school does offer some classes in large lecture halls, they are usually the first year introductory classes in courses that a lot of people are required to take. As you go further along with your studies, your classes would proportionately get smaller, as the number of people required or wanting to take the classes gets smaller. In some cases, after a lecture in a large lecture hall, follow-up seminars are scheduled later in the week with students broken up into smaller groups in which the students have a chance to participate more actively, ask questions, discuss points of interest, and in general, process more fully the information that was presented in the large-group lecture. This is not always the case, however. For some classes at some institutions, all instruction (particularly at the introductory level) may be presented in a large-group lecture format, so when you do your research, it will be worthwhile to find out exactly how classes are structured and scheduled at the institutions at which you are looking and to discover whether or not follow-up seminars are part of the instructional plan.
