By having a good rapport with the students is key to being able to help the student. Day 1 of each class I give a bio of myself, and allow all students to do the same thing. We find similar interests and by the end of week 1 everyone helping each other. If a student asks a question you can not answer, or you need more information, make sure to answer that student within a timely manner. This means so much to the students and it keeps the rapport up.
