Further help and Advice
- Confused about the material? Your first resource should be the office hours offered by the teaching assistants and me. Office hours are also a good time to give me feedback on the class.
- Please write neat and complete solutions to the problem sets. "Neat" means well structured, not only esthetically, but also logically. "Complete" means that the grader will need to see a sufficient amount of explanations and details to give you full credit, even if the question only asks for a numerical answer.
