Mentoring and tudoring are great ways to assist some students over a hurdle, but how do some of you handle the ones that do not have the basic knowledge of the topic required to even be in your class? When you realize they have somehow made it to you but they are completly lost....what do you do? What about many students seeking your help at the same time, not another tudor, but you. I teach a course that is very advanced, and some students are afraid to ask questions, this sometimes leads to a "Can I talk to you after class" line of students seeking private help from me. This can be overwhelming to say the least. What are some ways you would suggest handling these types of situations?
