They come in different subjects, so the covers will be different. Just make sure that if you buy the book that you match it to your textbook. They offer them in a variation depending on the textbook your class carries. If you're interested in seeing a Con Law one for example, you can dm me! I have a PDF copy and you can browse through it to see if you are interested before purchasing the book. But I like the way it breaks down the summary, holding, and it has key notes on the side, so you can see what topic you would find this to be tested on. I used it in the last two years of my law school career and it has been a game changer for me. I can also testify I name dropped cases so easily in con and civil procedure because I got the meat of what the case was trying to tell me from this book.
You can use the book as a guide, supplement, or read it in place of long cases. Up to you how you use them. The night before exams sometimes I would browse quickly through this book and it was easier.
Also everyone in my class used quimbee and the professor knew quickly. So by using these books I didnt have to rely on sources my classmates were getting caught for using lol
