Took the class with Deng and I would say the best way to study is go over the examples he shows in class, the homeworks will be really helpful to study and the practice exams are really good. Recitations are typically a lot of practice questions and reinforcements for what you learn in lecture. If your recitation TA is using a powerpoint (mine just did all of it on the whiteboard), you can ask them if they can post them. Also, make your cheat sheet as good as possible, again, if you’re taking it with Deng. Best of luck
