This course is challenging and sometimes you will have question regarding the content of the course. More often it is not immediately obvious how to solve problems. First look at the class text book for examples to assist you. If still stuck then talk to your colleagues in the class. If you still need help, talk directly to Professer Cline or the workshop instructor, we welcome discussion out of class. We have office hours but will help at other times if available. You must learn to solve problems yourself but do not waste excessive time struggling when you are completely lost on some problem or topic.
