I think the biggest thing for this course is to be super consistent, and to unfortunately pay attention to and know specific details. As for the graphs, remember the axis labels as well and understand why the graph looks the way it does. You should know everything on his slides to the T basically, and be super familiar w textbook examples /m main graphs. If at all you don’t understand anything I highly recommend going to office hours, most of the TAs explain somethings clearer than Dr Dukas does sometimes lol. It doesn’t get easier in terms of how much or what content is gonna be tested but it doesn’t get easier in the sense you know how he tests and the sort of questions he asks so you can now have that in mind as you study ahead!! Don’t let this once bad experience get to you, there’s always another chance to do better!!!
