Faculty members are available during their office hours, whose collective list is posted on the Faculty website at the start of every semester. Since academic life may present new and unexpected complexities for you, do not delay to ask for their help and advice immediately when a difficulty arises. Waiting until the end of the semester to declare to the professor at the very last office hour that you “didn’t understand anything” in a given class will not be of any benefit to you. Remember: Faculty members are there for you, but you have to let them know first!
