Try to influence them to sit near the front of the classroom. In order to gain a valuable experience from a lecture, you should be actively involved. Too many students consider a lecture a passive experience, and for many it probably is. However, if class is going to be worthwhile, you must participate. If an instructor poses a question to the class and you think you know the answer, do not hesitate to raise your hand.
Instructors generally appreciate a student who consistently attempts to answer questions.
Participation is a clear sign that a student is paying attention to the professor. There are times when you will have a question about some point in the lecture. It is best to ask this question as soon as possible after the instructor states the point. There are times though when it is not appropriate to ask right away. In that case, write down your question and ask it when the instructor asks for questions or when the class is over.
