Solid State Press
We took the textbook apart and gave every topic its own short book.
Each book in the TLDR series covers one specific topic in roughly fifteen pages — what you need to know, how the ideas connect, the kinds of questions you'll be asked, and worked examples that show how to think through them. Read in one sitting.
