Some lectures have accompanying notes that explain concepts in greater detail. If they are useful, great; if not, ignore them. You are not responsible for concepts that are not discussed in class.
Take a look at our textbook. You do NOT need to read the whole book - just use it as needed to clarify points discussed in class. That being said, some of your predecessors have asked for a reading list to go along with each lecture. So here it is: a list of suggested pages in Robbins.
You can always email me, even if it's a question on another professor's lecture. Or if you just feel frustrated.
